For steppers, why not look at keling? you can get the motor AND the drive from the same place, and they can help match the package for you.
I built many cnc machines, and when using components that come from differn't places, if something don't work right, the drive manufacture simply point their finger at the stepper/servo motor manufacture, and the stepper/servo motor company points their finger at the drive manufacture. No one takes the blame. If you get them from the same place, you have that potential problem solved. I believe you can get the power supply from Keling also, now you have that matched with everything also.
I installed some Kelings and liked them.
Good Luck,
