I have a Master Forge, propane, $150 at Lowes
Pros
Propane - controlled heat, no wild swings in temperature over long periods of time
Huge - lots of room inside, I have yet to need more room
Cheap - need I say more?
Venting - venting on it is great to control the heat
Cons
As you will read about, the door needs a gasket, easy enough to do but I have not got to it yet
Water pan is too big - it blocks too much heat, in the winter I have to use a smaller water pan to get the heat up
I have smoked ribs, chickens, roasts, a turkey, cheese..... I love everything in the smoker, it's fun to experiment.
I wanna smoke something now
