There are $60 switching power supplies from China. I bought a CNC kit with the stepper motors and stepper motor drives and the power supplies and it came with three of these. They're available in 300W and larger sizes, with little difference in cost.
http://www.ebay.com/sch/i.html?_sacat=0&_from=R40&_nkw=%2860v%2C+60+v%2C+60+volt%29+switching+power+supply&_sop=15 I've ordered a lot of these for various CNC projects. Buying them not bundled in a kit has resulted in problems with shipping. One company put the power supply in a plastic envelope with no packaging and dropped it in the mail. They're usually shrink wrapped or packaged in thin cardboard "gift boxes" which are inadequate for shipping. The only way to get one to survive is to put in in a sturdy outer box with some surrounding bubble wrap or similar packaging, but most sellers don't do that. You might offer to pay extra for proper packaging, although that shouldn't be required. It should be the seller's responsibility IMO. If you can get one to arrive that doesn't have components rattling around inside, they're usually quite reliable. Or, you could shop eBay for a suitable transformer, bridge rectifier and large electrolytic filter capacitors and build your own linear power supply. If you don't mind paying a bit more, there's always the very nice AnTek toroidal power supplies. They package their supplies very well. http://www.antekinc.com Good luck!
