While they aren't as good as 723-based designs, three-terminal
regulators aren't that bad.  They are in almost all the gear you own
that plugs directly into the mains, with the exception of tube gear
and power amps.

Can you fit the 800mA supply??  That's what I have, and it is a
723-based design.  Although I probably should buy a bigger supply.
Occasionally, it freaks out when I turn on the modular.  It didn't
before, with the same modules, but I changed my distribution using
the newer MOTM boards, which for some unknown reason have these huge
bypass caps.

Imho, you can buy a better supply for less money than building one
yourself.  If you need a 723-based supply, and the Power One 800mA
takes up too much space, then maybe you can get one from a different
manufacturer.  Or you can but it in a separate box.
