PSU design?

[Per Mattsson]

I'm about to build  a new +/-15 v PSU. Currently I'm choosing between two
designs, either one based on 7815/7915 or the Digisound 80 design using
two uA723C's.

It's meant power a modular unit with your average mix of oscillators,
filters, mixers,  weirdo circuits etc. I probably need a second +5 v PSU
to drive those digital ICs but I already have a small computer PSU for
this. 

Any thoughts on what to design to use?
