How about old Lab supplies?

Tweakers' Asylum

Tweaks for systems, rooms and Do It Yourself (DIY) help. FAQ.

I like the aesthetics of old HP lab supplies. A dual supply will allow you to do both at once. Of course, they are complicated devices, and many are pretty old. Calibrated, lab ready units are expensive. If you shop carefully, you can find something working and warranted for $25-75 (the links I posted were hastily found examples, not suggestions). They are a bit of crap shoot, but if you love the look as I do. . .

You could also consider building something. Little regulated supplies are very simple, and there are kits floating around.
