If you're going to get any kind of Gecko for this application get a G540 - handles all your axes at once (except the second head).
But that is also a 15V part IIRC. But that's ok - the only reason the Makerbot uses a PC power supply is because they are dirt cheap and TUV certified. You can use any supply you want. I use 15V supplies. I ended up throwing away my cheap Chinese junk stepper drivers because they kept missing steps when coming out of idle. I run Keling KL- 4030's which are inexpensive and have worked well for me. Also, probably doesn't make a difference, but I got an UP! 3D Print head and the thing has been bulletproof from day one. But you have to keep the fan running.
