I was just looking at these printers today and getting as much info as i can. I'm looking for a kit printer, not so much for the $$$ savings, but mainly because I wanted to assemble my first printer myself. I too saw the amazon reviews putting the 1up and 2up in the 3.5 to 4.5 out of 5 range, but read A LOT of reports of missing parts and bad customer service. I don't mind replacing screws or faulty parts, but my only concern is bad software and cheap electrical components that will stop working properly shortly after use.

Given that you have not recieved a response since December of last year, I believe that's the final nail in the coffin for me: this is probably not the DIY printer i'm looking for.
