Hi Jack
I spoke with you once before, I'm from Moose Jaw. Anyway, I also have a Bradley. I have mine built into my heated garage and I've done a number of mods to it as well. Works flawlessly. I know a lot of people "think" the biscuits are expensive but they are really not that bad and makes the unit pretty much set & forget. I have found a supplier here in Canada that is by far the best price I can find and I would be happy to pass his name along to you. The OBS is the model that's on sale at Canadian Tire right now. The DBS, although it's digitally controlled does have some temp swings, typically 10 degrees each side of the set point. They don't have any effect when doing butts or ribs, however if your doing sausage or something like salmon you want a little tighter control. The OBS with a PID is around the same price as a DBS but the temps will stay within +-1 or 2 degrees.
Anyway, if you would like any other information let me know, I'd be happy to pass anything along to you.
Mike
