Personally I have used a model very similar to this over the last 20 years:

Frankly, I have had my share of problems with them. I have probably owned 4 of them. The burners will eventually rust, get clogged, etc. One of them had the regulator stop working.
At this time I am looking to see what others BBQ on. I want something in a similar size since it is very compact and convenient. Propane or other fuel is a must since some areas do not allow for charcoal.
What do you guys use?
