I'm sure that if you ask nicely, one of the guys on here will make you a PSU for cost price + a couple of beers.

Wouldn't be the first time ;)
Get the bits sent to me and I'll solder it up for you - it wont take more than 15 minutes. In fact I think I have a spare new 500VA toroidal transformer... 4 motors at 3.5 amps, so you need about 70% of 4*3.5 which is 9.8 amps. 9.8*50V=490VA ... so the transformer I think I have is perfect.Last edited by Jonathan; 25-08-2013 at 11:15 PM.

Jonathon, wouldn't it be easier for you to buy the parts, make the PSU and send him a paypal invoice? There seems to be a serious lack of decent quality PSU's on eBay...

The mains things are;
Capacitors:
SNAPIN:4700UF/63V Panasonic (ECES1JU472N) 25.5 X 50 | eBay
Transformer (other places have them too):
Toroidal Transformer 500va 0 50v 0 50v
Rectifier (excessive rating, but means you don't need a heatsink so it's easy):
KBPC5006 Bridge Rectifier 50A 600V
Plus you'll probably want a fuse holder and a switch...
