It's going to boil down to, How Nerdy do you want to get, or how Hands off do you want to get.
Some people like the push a button and not worry a heck of a lot of it path. Others want to nuke it and play inspector gadget and be intimately involved in every second of the roasting experience. Granted these are the pretty much extreme ends of the coffee roasting spectrum but you get my point.
Some people love to build stuff and make frankenroasters, others are not that inclined or ambitious and just want something someone else did.
The 'marketed' roasters are more towards the plug and play crowd. The SC/TO as an example are for the home tweakers and gadgeteers.
I like my Behmor, I learned how to use it. I have one at work that I tricked out badly, I have one at home that's just 'basic'. I have heard others complaining about them lately, maybe the quality is suffering since they first came out, as is pretty much anything made nowadays as china takes over the QA on everything. Maybe it's just because there Be mor of them out there, (that's for you John

so since more are out there, there will be more with problems. I don't know to be honest.
In this case nobody can really tell 'you' what 'you' want / need etc. You are going to have to ultimately make that decision based on what you want to do, how much time you have etc etc. How 'involved' do you want to get with the roasting? To put it another way, I don't want to tell you get an ABC roaster they are great, only to have you try it, decide you don't like it, now are mad at me and it's MY fault because I told you to get it.
How old is your 'more, if its under warranty can't you send them in to get fixed or did he stop doing that?
