That leaves just the breakout board which ive still got to check on but a cheap as chips one for £20
Three 3Nm steppers here for £82.19.

What features do you need from the breakout board? Since you're now on a tight budget, if you're not bothered about controlling the spindle and stuff from the computer you don't need a breakout board. The PM752 (or any good cheaper drivers on eBay) are already optically isolated, so the breakout board does not add any more protection for the outputs. It just makes it slightly easier to wire up. Just thought since you're happy to make the PSU you might be happy to consider making a simple breakout board...
