I own and use both Bradley and a Cookshack and I'd suggest the Bradley is probably not worth the total costs involved over the long term. Here's the math.
Their proprietary "biscuits" will cost you roughly a dollar per hour of run time. If you use your unit an average of 20 hours per week you'll be spending over $1000 per year to use it. That's more than twice the original cost of the unit, every year, forever. Ouch.
Add to that the fact that if the company goes under and no longer produces the biscuits the unit is useless, except maybe as a holding oven.
What the Bradley does make sense for, IMO, is cold smoking. I bought the smoke generator (not the entire unit, just the generator), built some custom cabinets, and with a few other mods I'm now able to cold smoke for 16 hours of 100% hands-off operation. Since cold smoking is a big part of my operation, and since the costs are more than offset by labor savings, it makes sense for me in this very limited role only.
Hope this helps.
