I'm using a fairly new Astron RS-35M here with an Alinco DM-340MV as back up. I much prefer linear supplies to switching ones.
Both are good supplies in my opinion. I've used the Alinco for 3 or 4 years with zero problems but got nervous about the Alinco's lack of a overvoltage protection circuit, and fan noise can be a minor annoyance under heavy duty cycle. There is no fan on the Astron to make noise (just heavy heatsinks) and I like that. The lack of voltage regulation on the Astron meter lighting circuit causes the lights to vary as a function of load on the supply, why they designed it that way I'll never know. I plan to either just cut the wire to the lights or go with regulated LEDs. Without regard to brand I personally would look for a supply with overvoltage protection for the load (versus various circuits that might protect the supply). Otherwise any failure mode in the supply that causes loss of regulation and significant increase in output voltage could severely damage/destroy your expensive rig(s). A shorted pass transistor for example. I believe most all the Astron's have crowbar circuits.

What are the popular and reliable supplies being used these days? If there are some to seriously stay away from, please so state.
