I'm a Bradley baby... absolutely love it... for exactly the reasons you listed. The biscuits mentioned here are no problem, the fact is, they're just easy to work with. No need to worry about low temp smoking as the biscuit feeder has it's own heater and feeder. Just load up the number needed to smoke for the time required. 20 minutes per biscuit, if you need 3 hrs smoking time, you put in 9 biscuits plus 2 to feed the full amount. Set the timer and set the temp.. go watch your favorite show, go shopping, hit the range for a few hours, it's that simple. As for the wattage, you just want to make sure you don't have some long azzz extension cord causing a voltage drop. Don't get the 6 rack Bradley, stick with the 4 rack, and get the one that cost around $350 on Amazon.. You can purchase the biscuits from Amazon or Cabella's. I always just purchase online at Cabella's.
Also there are lots of recipes online for smoking with the Bradley, BBoards with lots of info like we have here. As for Bradleys support, I messed my smoker up the 1st time I cooked pulled pork, I closed the vent on top and messed up the pork, the paint around the trim and on top of the smoker got messed up. I emailed Bradley, they had me send pictures of the damage and sent me a new smoker!!! free. Great customer service and they went over and above, as it was totally my fault. The instructions even said to not close the vent!! But I was cooking in the middle of winter and thought it would help in keep the temp up.. I learned quickly that instructions are made to be followed..
