Motor costs and links and 5 axis software

I think I have decided on the shopmaster. Is the gunmaster with the
quadra lift. I am going to start out with 4 motors. I will have 2 rotary
tables. One 8 inch and a 4 inch. The 8 inch mounted flat on the table
base and the 4 inch mounted on the 8 inch at 90 degrees. I would also at
some point also like to take a crack at titanium for my radio controlled
stuff. So can I get some advice on motors first. What size guys?
Should I really go with the servos? Will they make that much of a
difference? Can I get some links to some good prices for both servos and
steppers. And will the gecko drives run at the power that I think I
want. Boy I can't wait to start getting stuff so I can really make some
mail.
