Best PSU for positive and negative ground?

[momo]

Im about to build a Psu for my pedal board, the thing is I recently got hold of about 20 Ge PNP's and Im starting a collection of positive ground effects!!...I want to be able to power my setup and mix and match my collection regardless of ground type. So Im looking at the spyder Psu with isolated supplies, that is what ive seen so far that looks the best.
What do you guys think?
