with the down turn in indiustrie, look for a used knee or bed mill, it will be bigger than you want, but I have seen a few mills with a 25" X by 12 Y 3 axis going cheap for under 8K, same with some of the small teach & turn cnc lathes
there were a few desktop cnc lathe from schools that had 4 & 6" chucks, good luck in your search, do not forget the shipping fees, and who will pick them up for you
