I used to power my station with an Astron RS-20M (20 amps with front 
panel meters) linear power supply, but found it to be marginal when 
using my RF Concepts brick amplifiers (they are 170, 110, and 100 watts 
respectively on 2M, 135cm, and 70cm).  I'm now using an Astron RS-70M 
(70 amps with front panel meters) and I'm quite happy with it, except 
when I have to carry it up the stairs to bring it out to Field Day. . .

I'd worry about using a switcher generating RF hash, although QST gave 
the MFJ switchers a clean bill of health in that regard when they 
reviewed them a couple of years ago.
