Here's a question... I get a lot of laptops minus their PS's. The ones
that are 12vdc or 9vdc with a standard plug are no problem, but the ones
like the outbound (I'm lucky enough to have a PS) or the GRiD's (17.5vdc?)
or whatnot aren't even covered by the select-a-warts from Radio Shack.

So, does anyone make a box where you can set it for whatever voltage you
want from, say, 1vdc to 50vdc or something, with some way of hooking up
different plugs? Does anyone know where to get such a beast *cheaply*?
Thanks...
