I personally use Astron for most all the shack 2 70 amp supplies a VS and a RS-70M but also have 2 Samlex supplies and they are very quiet. Both of the Samlex supplies have been on running 24/7 for the last 6 years one is a SEC-1223 (23 amp) the other a 1235.
In a recent issue of QST magazine they compared power supplies for quietness/RF/reliability the Samlex SEC-1223 came out as a best buy and only $99 new retail. I would voice that opinion also.
