How about this low-cost unit? I doubt you can really save much if you go the DIY route.

I don't know what happened. I can't seem to make an EBay URL work in the post. Let's try it as a TinyURL:

well the amps are relativly cheap so I want to evaluate some to see which I will stick with as a main build,and they seem to all have voltages all over the spectrum.
