I had a Refine cutter for a while.. it was noisy to cut but did the job OK.
You will still need to make your cutting files in a vector file this can be as simple as a pdf but your software needs to be able to handle it and talk to your cutter. Software costs more than the damn cutter.

I have a sign software CD here that i never used.. let me see what models it supports and you can have this and then buy the model to suit... hows that sound?
