CrazyRed, I would stay away from the Bradley and I'll tell you why. First of all the wood bisquettes they make you use in that thing are VERY expensive. Its $20 for 24 of them and thats not enough to smoke one pork butt. If you read the article that Dave Naas wrote at "The Charcoal Store" about the Bradley smoker you will see he went through $400 worth of wood bisquettes in no time at all. If your going to be cooking commercially you would go bankrupt trying to keep the thing in bisquettes.
https://www.charcoalstore.com/kb/article.php?id=008He also describes mechanisms that run the thing and look at the pics he put up. Do yourself a favor and stick with CookShack. Their products are higher quality, in my opinion, their customer service is the best, Period. The only thing you might do is maybe consider one of CookShack's commercial models rather than a residential, may fit your needs better.
* I edited this down a bit cause I dont want to be considered a Bradley basher, or a basher of anything really. I just get emotional when people compare products cause I love my AmeriQue, and CookShack, so much. Sorry guys if I came off a bit strong.
