Was just mooching around on the net and came across these stepper driver/control interfaces.

Look pretty good all compact design.

Nope, not seen them.
Pro's: (in my opinion...)

Compact
Parallel port on driver, so less wiring
Coolant/switches etc are easy to wire


Cons:

A bit expensive, £190 at current exchange rate...could get 3 PM752 70v, 5.2A drivers from Zapp for that with money to spare.
Parallel port being on driver makes it more difficult if you want to use some pins for other things
48v is reasonable, but more would be nice!
You can't run many big motors in parallel with only 3A.
Spindle output is a transistor, relay would be much more useful and in-keeping with the design.

£190 plus import duty, plus Parcel farce handling charge, plus Vat will make that closer to £254.
Three drivers from ARC at £42.50 each including shipping and vat = £127.50
System 1 board from Roy at DIY-CNC £41 including postage
Add a further £25 if you want the spindle board,

Job done for £193.50 from UK suppliers and if you do manage to fry a drive you don't have to replace the whole lot
