Been smoking for a year now with my masterbuilt 7-in-1 and I feel that I need a little more space, plus if I'm smoking something I can't use my grill. So I have been studying the following smokers: UDS, WSM, and the gosm big block. I like the cheapness and the capacity of the UDS but I would want to do one with 2 grills, and I don't like that its not very portable and hard to get in and clean or access meat. Also probably wouldn't be quite as efficient as a WSM. I like the WSM for its efficiency, ease of use and ability to take it apart. Now to throw the gosm in the mix, love the size and capacity, like the gas, but would like to be able to use charcoal if i wanted, don't know about quality of the product or how good the meat it smokes is. If anyone can help me that would be great, it is quite a dilema and my wife doesn't want me to spend much.
