Do you thinks above information is usefull, and do you know how to clean the stainless steel grates after you have a wonderful BBQ with your friends.  I think it is very boring work and this solution will help you save times as well as make the work of cleaning more interesting.

Okay, this is marketed as a charcoal grill, but its ability to hold low temperatures for an incredible amount of time has made it and other Kamado cookers very popular amongst smokers. Giving you the best of both worlds, the Big Green Egg may just be the only piece of outdoor cooking equipment you'll ever need (because it will probably last longer than you will).

Another review post of stainless steel charcoal grill for barbecue you should take a looks

This is the grill that launched Weber. While there are lots of imitators this grill is built to last and has superior cooking abilities. The round design focuses heat and the multiple vents allow you to control it. This one charcoal grill can do most everything including smoking on a limited basis. The large grilling area gives you plenty of space for direct and indirect grilling. You can even get an optional rotisserie kit.

Easy to use and highly durable, the Old Smokey 22 inch charcoal grill is perfect not only for your backyard barbecue, but can be taken most anywhere since it only weights 19 pounds, making it a great portable charcoal grill as well.. Made of aluminized steel, the Old Smokey #22 has no paint to peel or burn off and it taken care of can easily last for decades. Because of the tight construction you can hold temperatures down for low and slow barbecue. This charcoal grill comes from a small company in Texas (where it is still made) that has been in the same location, making quality products since 1923.

The best feature of the Portable Kitchen Cooker is its amazing longevity. Stories of people using these grills for more than four decades are common and the current version of this grill is identical to the one that Milton Meigs first invented in 1952. The design is primative, some would say retro, and simple. It is this simplicity that makes it a great grill capable of high temperature grilling and low and slow smoking. The only limitation is the small size. At 301 square inches it is only a little larger than an 18.5 inch Weber Kettle.

Some people manage to get it right the first time. Grant Hastings got it right when he built the first Hasty Bake Grill in 1948. This charcoal grill has changed little in function since then. Basically it is a closed box with a charcoal pan mounted so it can be adjusted close to the cooking grate for high, direct heat, or lowered as much as 14 inches to low temperature cooking. Add the removable heat diffuser and it grills, smokes or bakes indirectly. This makes the Hasty Bake design one of the most versatile on the market. There are many models and this version, the one of the least expensive, starts are around $1,000USD, so this isn't an inexpensive product. However, the quality construction (made in the US) means it will last a very long time.

In 2011, Napoleon reinvented the kettle charcoal grill with a new design for airflow that helps create an even charcoal fire. For 2012, they have taken this grill and mounted it into a metal cart with folding side table, providing workspace and stability. While more expensive than most metal charcoal grills, this grill has a extras that make it worth the increased price, particularly the heavy cast iron cooking grate that fits into three positions and is hinged to allow access to the fire. This charcoal grill is comparable, very comparable to the Weber Performer charcoal grill.

The Broil King Steel Keg is so closely modeled on the size and shape of the Big Green Egg that grates and accessories are interchangeable, yet this metal version has some truly impressive innovative features and design. Capable of hitting very high temperatures while staying cool on the outside with great temperature control, this grill really is an amazing unit. You can even mount it onto your trailer hitch and take it tailgating, something you would have trouble doing with similar ceramic kamado cookers. While a great grilling grill there are some small problems with the design that might give you issues.

This is about as close as you can get to the convenience of gas grilling in a charcoal grill. The performer uses a 5 gallon propane tank and burner unit to light the charcoal for you. All you have to do is pour in the charcoal, push a button and wait for about ten minutes. Then you can turn off the gas and start grilling. The performer is designed to be a complete cooking unit with large storage area, easy clean up ash catcher and working table space.

If Q, the James Bond weapons maker, was invited to a cookout, he might show up with one of these. This is a 7-skewer, charcoal fired, Brazilian style rotisserie cooker, that folds up into a metal suitcase. Literally in minutes you can set this unit up, light the charcoal, and start cooking. Pull off the skewers and just like in the Brazilian steakhouses you can walk around carving steak, sausages, vegetables, and pineapple onto peoples plates. Of course at around $720USD this isn't an inexpensive solution to churrascaria style cooking, but it certainly is cool.

First of all this is an expensive grill. At about $2,500 it is one of the more expensive charcoal grills on the market. It is also a very basic grill. Though it comes with a rotisserie kit is doesn't come with a lid. This is pure grilling. Heat can be adjusted by a rotary crank that changes the cooking grate height. It is completely stainless steels and a great grill for grilling, if you want to spend the money.
