RuggedCircuits:
It works pretty well. Watch out for power supplies that have minimum load (current) requirements. If you don't draw at least this amount of current from the various supplies, it will not regulate properly and you could end up toasting something with improper voltage (e.g., the "5v" output ends up at 6.5V or something).
Thanks for the warning. I had heard about minimum load requirements but I wasn't aware I could toast anything if I didn't meet them.
