Master build 30" or 40" electric is set it and forget it. I got the 30" and would like to update to the 40" for more room.
With the a-maze-n smoker i can run for 6 to 8 hours of smoke and never have to worry about temps.
If I am on a longer smoke I can refill the A-maze-n with sawdust and off we go again.
Just did a Boston Butt this weekend for a neighbor and I was only there for the beginning then off to bed about an hour of the middle (recharge the sawdust and check the temp of the meat) and the end of the smoke last hour to get it done. Came out perfect.
