David,
When I purchased my HobbyCNC kit I purchased two of the power supplies recommended by HobbyCNC. If you and Joe think it will work and you would like to try it let me know. I'm just over the mountain and it would probably get there by the first of next week if I send it out tomorrow.
I also have the Xylotex kit however I'm no where near set up to try it for you. It will be a while. Let me know.
