A while back, I asked Billy of BDTools on eBay to make me a kit for the G0602 lathe I have had sitting in the garage on the floor for 2 years. He finished it the other day, so I am headed out to pick it up. I will post a report on accuracy, etc. once I get it installed, but it has ballscrews on both axes and looks like it'll do quite nicely. He posted a couple of videos for me to look at in case anyone's interested:
