Well here's a twist for an opinion. I just love this unit. It is not the machine for large print jobs, but for small quantity varied work it's perfect. If you run 20 or 30 small decals or a few signs, lables, small graphics, etc, the machine will do fine. I bought mine about 15 months ago. I suppose I was lucky, it was sitting in a warehouse as damaged goods then found it's way onto ebay. It was originally a return back to one of the distributors from the papers I fouind. The machine was dropped on it's side which bent the frame and to many I suppose it was now junk. I gambled on it, got it, found it was brand new inside, not ever used. It would miss the cartridges on pick-up routinely. I pulled the cover off put a square against he side frame and simply pushed it back level. It hasn't missed a cartridge since. The only problems I've had all have been other than the machine itself, the same kind of issues I'd probably have with any other machine when software glitches, etc.
I printed a few test decals 15-16 months ago and stuck them outside facing the day and afternoon sun. They haven't faded and look just about as good as when I printed them, so it's a really durable print system.
If you can find a working model that isn't worn out, and if you are going to be doing small quick jobs with it, I'd say it's ideal. Most of the printer guys I know generally dislike the machine. I suppose it's all a matter of what you need to do with it. MY business is motorcycle decals. I need a highly durable print that can withstand the harsh elements and be resistant to fuel. I got that with this machine. While Zeronine has decided to stop providing ribbons for it, I took the plunge and set up to have ribbons made for me. The ribbons are not nearly as expensive as one might think when buying them through the standard channels. I hope I can use this unit fo rmany more years. So count me in as a strong positive for this unit under the right application.

P.S. I"m buying any used PC-600 cartridges if anyone here has them to sell. I prefer the Roland but will consider any of them.
