Building a power supply is too much of a chore!  I've found some very
hefty Lambda rack-mountable power supplies on the surplus equipment market
that give just the right voltages and PLENTY of current.  Relative low noise,
too.  "Impressive" metering.  One or two needed the panel repainted or
chromed (for effect).
