Many people swear by Unicomp, but I had that bad luck that I first paid for the thing, got the thing, and then read that as of recently, there had been problems. Problems with quality, problems with output. Then they went so quiet people thought they had gone out of business, then they resurfaced. By that time, I've had an original Model M and two different OG Model Fs. When I buy old stuff from eBay, at least I have my expectations calibrated to the fact that this shit is real old.

Your unit must have been a couple years older than mine, so it just might be of that more legendary quality. Yours is from at least 2008, right? You may even had got it before markets went bonkers!
