Here is a Power Supply I use for my Arduino Projects.
It is a 24v 5a MeanWell and two POWER SUPPLY MODULE M2L8 from ebay.
I stuffed it into an old case. Total cost was under $70.
Fits perfectly under my Fluke 45!

nice job on this.  i do agree on your statement though its definitely not cheaper to build I could have bought at least one used HP off ebay by now with what Ive spent on parts for my PSU.  but I'm building it as a project to learn so from that aspect I think its worth it I am learning a lot.

 Hmm, now that I should duplicate - since I too have a Fluke 45 I could slide a power supply under.

A radio shack 12v 'Battery Eliminator' with a chinese CV/CC module in it.  Hard to end up with a smaller package on your desktop and still have CV/CC, although I doubt that without better cooling its ability to provide more than about an amp.
