Tal,

I'd recommend building a power supply, especially if you have not built one
before.  If you have, then ignore this message.

When I hire a new technician, I tell him he'll be needing a variable power
supply for his bench, and he must build one.  It's sort of a rite of
passage, and if the guy can do a neat wiring job on his benchtop wonder,
then he's good enough to wire something else.  Building them is a good
exercise for the new engineer.

I often start with a car battery charger.  Good high amperage transformer,
heavy diodes, and a case, all in a cheap mass produced package.  Add a
voltmeter, a few capacitors, inductor, big pass transistor, a PIC and a
knob, and you've got a nice bench power supply.

Of course if this is "old hat" to you then just go buy one.
