Benchtop power supply

Can anyone suggest a good bench top power supply and where to get it? I'm
starting to play with stepper motors, and my wall warts just aren't cutting
it. I'm tired of trying to find just the right one with enough capacity for
what I'm driving.
I'm not allergic to spending a couple of hundred dollars, just as long as
it is a good one.

Dual outputs? Adjustable? Anything I left out?

This is kind of off topic, but I'm betting you guys are a pretty good resource.


Thanks,
-John

    You should be able to pick up a 2-3 amp 0-30 volt DC supply with adjustable
    voltage and current for $100-200 depending on the quality. This should work
    for the smaller steppers and most any motor you would use on a normal size
    robot. They are advertised all over in Nuts & Volts.

    Dual output is cool for op-amp work, just be sure you can turn the voltage
    all the way down and that the power supplies can be tied together. One with
    a +5 and +/- 12 would be even better.
