I have a Copam 2500 sitting here with a cover on it. It was my first plotter. Prior to that, I'd never seen one, never used one, knew nothing about it. It paid for itself many times over in 3 months or so. I had some minor issues with it, but overall, it was a decent plotter. Biggest issue is it's not USB so you'll have to work that out. I bought several serial to USB converters and never could get any of them to work right. Finally just bought a serial card for my computer and ran it that way.
It was a test for us. We knew nothing about any of it, and we felt we were getting screwed by a local sign company that was cutting our vinyl for us, so we thought we didn't have much to lose. If it worked, we would be ahead, if it didn't, we weren't out too much.
Less than a year into it, we decided we needed to get a proper machine and bought a graphtec. I haven't used it since then.
If I had to do it all over again, I would just have bought the graphtec from day one.
It's not a bad machine.
