actually buying is a strong word for it.... most of them have been used the 
offset was free (rusted) the 
gas one i got was used 50 bucks nice burger grill but thats about it and the 3rd 
is this leaky p.o.s.
the gas one was neat in theory but the indirect flame means it smokes by grease dropping onto a pan and producing smoke 
and is great for hamburgers because there grey and you get no flare ups it turns chicken and pork grey and is just nasty.
so yea i been doing my homework and i really want a pellet smoker but not at those prices I know for what i am getting everyone says gas is better 
but not set it and for get it bottom line if i can get a good smoke flavor and 190 deg on a butt i will be happy with loading wood chips every so often in this unit
