I don't know what to say about the Behmor. I know the early ones were built like tanks. I know the guys at work in PDM used to burn the living crap out of their coffee because they thought that is the way it should be!! Their Behmor was black and nasty inside from all the super dark roasts they made the poor thing suffer through and it kept rolling right along. I know I have had a few nice fires in mine because of inattention / stupidity etc and a quick clean out run or three and it's still running good. I have heard more than once person complain now that the newer ones are problematic and just 'not built like they used to be'. Lately it seems to be circuit board issues is the main complaint I am hearing.
Are they being built cheaper? I don't know. Did he get a bad batch in, it's possible.
Before getting a different roaster, one needs to take into account customer service of a company as well. You are getting a new board out of it so that's a good thing, I have had good service from Behmor, and yet I have asked them questions on more than one occasion and never had any reply back.
Their product, I am happy with, I have never had any problems with it and I have had a few of them already.
Their customer service, Im going to have to say, my experience, hit or miss. Overall though I have to say I think it's one of the better buys for a 1 lb roaster for a few hundred dollars that you can back to back in if you really need.
