MO is that montana. If so what part.
If it was me i would use nema 34 motors and a 2 to 1 gear reduction thu a timing belt. Use gecko 201 microstepping drives or wait for the new Gecko Vampire drive. Use mach2 to control it. It has the abiltity to run 6 axis. Then pick up a power supply off e-bay. You can sometimes get them for $50 to $100 from the telcom industry. I had 2 nice ones given to me for free. Now I have a spair. To bad they are over 200lbs each. Get a cambel breakout board then your good to go on the electronics.
As for the table you did'nt mention size or need for rigitiy. Sure there are guys here with more knowlege than I that will point you in the right direction based on your needs.
