The money isn't the issue. (I'm cheap, but I am more of a buyers remorse guy, so I tend to try to buy one step above what I think I want, cuz I always "want" the next step up, sooner, rather than later, lol.) I originally started looking at $300 smokers, and am not here, haha.
I'm more concerned with adjustability and accuracy of the probes, and problems down the road. Cost would be about the same, for an analog, with PID and temp probe, vs a D series. Convenience of all in one, vs ease of fixing or replacing later.
