I'm designing my first router build but I've never used one before and I'm thinking of getting a cheap machine for a project to start me off. I've found an old Connect machine on ebay and thought about changing the control system to more modern standard kit but then I cam across one of these...

It has steppers but no electronics or power supply so I would get some experience of wiring, setting up and using a machine before I get let lose on a machine I've invested a lot of time and money on.

I'd look to machine some small guitar parts in wood and plastic along with some small pump clips for the micro brewery I work at.

Has anyone come across these and have an opinion on them?
