Bob's are cheap these days so worth a go before buying drivers i would say?

Wow, I had opened your link in another tab and have just seen it. I see what you mean, if that would do the job & connect to the driver board somehow I'd be flying!

Is there certain software needed to feed these boards or would the likes of Win PC-NC software do it? http://www.lewetz.de/download/hbwin2ecoe.pdf
