Yeah, horses for courses, cheap/fast/works and all that.

The cheap drivers work if you take their specs with a large grain of salt.
Here's one that at least labels the drive properly:
http://www.lightobject.com/1-Axis-CNC-Laser-Machine-Stepping-Motor-Driver-TB
6560-P451.aspx

The ones I have allow up to 3A, that one has 2.5A, either way I'd run them
at 2A. All the listing will have them at 3.5A, but that's peak (and doesn't
say how long you can run them for at that amperage).

That link give the voltage at 32v (35v max), again I'd stick to 24v. That
same site recommends 24v for the TB5660 drivers as well, see
http://www.lightobject.com/New-version-3-Axis-CNC-Laser-Machine-Stepping-Mot
or-Controller-TB6560-Support-Mach3-KCam-P274.aspx

24v @ 2A is a long way from 36v @ 3.5A, it's reality vs marketing.

I also have fan cooling on mine, I'm not sure if I actually need it.
