New mill

Well, new for me anyway... I have grown beyond the size constraints
of my Taig mill that I have been using (first with Master 5 -then
Mach 1 and now 2) and have bought a Bridgeport series II (like Tim
Goldsteins "Bridgett"). The Boss 4 control absolutely has to go and I
will run it on Mach II. I need to replace the antiquated steppers
that are on it with some good servos that will work with Gecko
drives - anyone know where I can get some good ones? I think 26 -35
in/lb motors somewhere near 2500rpm would fit the bill.
