Why not use a voltage multiplier - it would be a bit safer than simply
transforming up the mains, since then you don't need to worry too much
about the insulation in the transformer being good. Maplin Electronic
supplies do a laser power supply PCB for about #5.00 (yes I realise
you're U.S. based but if needs must.....), and in any case voltage
multiplier PCBs are easy to design anyway. The cost of this is likely to
be a bit less too, since all you need is a cheap isolating transformer,
plus a pile of diodes and capacitors. 

If you need to know more, or want Maplin's Address/Telephone number,
email me.

Hope this is of interest
