That configuration gets used a lot in precision work. Another option is the base from a Moore coordinate measuring machine. You can see a lathe built with one of these machines in this vid: http://youtu.be/TFmIuibVn3k?t=20s Those bases go for about $3k or so. Or free, depending on if you are in the right place at the right time.
