US micro has some reman levanos in ultra small form factor 10"x10"x3" tall size for $80 shipped. They work great for CNC. I got one and loaded it with XP immediately and it's perfect for running mach 3. It probably would have been ok with the windows 7 it came with though.
I have bought a lot of refurbished machines from them over the years and had an issue or two and their customer service is top notch too.
