Ditto.  I have three of the Power one supplies, two of which are the one
Paul lists above  Several of us have purchased these supplies surplus for
$20 each.

> 3) If you plan to use multiple 900PCB boards in a system, the
  *best way* is to run 16ga. wire from *each* board back to
   the Power One. They way *I* would do it is get a "barrier strip"
   and connect the Power One to it. Then, run wires from the
   900PCBs to the strip. *I* would use crimp terminals like what
   comes with the wire set in the MOTM-900. These terminals
   are at any hardware store. Crimping tools are cheap, too (like $6).

This is exactly how I do mine, barrier strip and all.  I have offered before
and will offer again to send FREE case-size lengths of 14 guage utility
grade wire to any MOTMer for this use.  We use MILES of this stuff at work,
and pieces 10-15 foot are simply trash at work, but great for home.  When
wiring control panels at work, our wiremen do crimp everything.  At home, I
solder the wire in the terminals (anal-retentive stooge stuff).

For those that are truly anal-retentive and want to have a MOATS (mother of
all terminal strips).  I occasionally get my hands on these used too.  They
are not your Radio Shack stuff, but are about 2" X 8" with 10 terminal on
each side.  We use them at work for 130 volts DC and they have about a # 10
screw that even "Larry the mad torquer" could not strip out.
