Stepper driver recommendations

[Agathon]

Just picked up a couple of nice Astrosyn 3.8Nm stepper motors - 4.8V, 2.8A.

Anyone have any driver recommendations? I'd prefer to source from the UK or EU. I need three. I already have a 36v 10A power supply so would prefer something that would work with this, but it's not essential.

I have considered these:

Generic 2DM542 http://r.ebay.com/pXWKfv
Generic M542T http://r.ebay.com/FRL6sh
Generic DM556 http://r.ebay.com/uo0ZFe
Generic MA860H http://r.ebay.com/7HVFKS
Leadshine M542 http://r.ebay.com/Jn7M8H

One last product I like the look of: Smart Drive Micro Stepping Stepper Motor Driver Unit SDONE484A 36B250 http://r.ebay.com/QNsNpq

It looks like Smart Drive have gone out of business as they're not answering emails and their phone is disconnected.

Thanks
