Hi,

You don't mention whether you you are after a compact, light weight, high efficiency switch-mode power supply or whether a simple unregulated transformer / rectifier with output filter would be adequate.

The best would be to purchase a manafactured one.  One can be gotten at: http://www.amazon.com/Tripp-Lite-PR60-Supply-Output/dp/B00009YFV0 for about $275.  The next step is to purchase transformer, diodes, and capacitors.  The starting place is looking at simple analog power supplies, they are all about the same but sizing parts is the trick.
