I've used wood, charcoal, and electric. I am looking at venturing into the world of a gas powered smoker. I have it narrowed down to 3 very similar units. I am not sure whether I want to go with a Smoky Hollow, a GOSM, or a Perfect flame. All seem to be very close (with the GOSM seeming to be slightly wider, which has it in front at the moment.) They are all within about 4 bucks of each other at local retailers. Any of you all have a preference? Ny the way thanks for the outstanding forum. Glad I fell upon it.
