I recently go into smoking and have loved it. Only time the wife doesn't complain about having to eat meat...
My smoker is a cheapo cabellas one (made by masterbuilt I believe) that I got off craigslist for $50.
Planning on doing a fridge build in the near future.
I'm a software developer by day and a semi alcoholic robotics enthusiast by night. When i get around to the fridge build i'm planning on building my own controller from the ground up so that I can tweak it just right.
