Ok the bottom line is that large steppers need Mains voltage Drives to get any speed from them. Like Ger says 110v will only get you limited speed.

If using R&P then you 100% will need Servos because they are so much less efficient than ballscrews so with heavy gantry like this you will need really high torque motors and Large steppers just won't give the speed you'll need.

Servos from China are now so low that it's No brainer to me that you need to look east.! Approx $400 per set drive/mootr/cables.

However be aware that you'll also need match the rest of the electronics to match so you'll need an external motion control card with high pulse frequency to get the full speed/smoothness of the servos.
