Hey GB, I had one a home-made one (not made by me - no skills) that I really liked. Let it go when I got a bigger model, but I miss it now for my backyard rig. Here's a link that talks about some of the likes and dislikes http://smokingmeatforums.com/forums/...ad.php?t=17376
Ask yourself what you are looking for in a smoker. How much meat will fit on one rack? Remember that the rack closest to the fire box opening will get a LOT more heat, possibly even direct heat, than the upper racks, so don't plan to use the bottom ones much. How thick is the metal? For the price, will thin sheet metal (if that's what it is) that will rust away in a couple (?) of years be worth it? How big is the firebox? Big enough for sticks or chunks?
Got any specific questions?
