Hi guys, and gals! Briefly, I've been bitten by the smoker bug and am looking to upgrade my el cheapo Brinkmann. I live in the mountains of Colorado, and am interested in a unit with some insulation so I can smoke in cold weather. I have a sheltered place, but air temps will be chilly. Volume isn't a consideration, since I will be doing three butts max. My budget is about $1500, but I could go a little higher. Ideas?
