Can't go wrong with an Astron. My RS-35 has been running steady for 
over ten years now. The last year it has been powering an IC-746PRO.

The RS-35 is a linear-type supply. I would avoid a switching type 
unless the manufacturer guarantees no interference in any band. I 
have a UPS with a switching supply which ruins low band reception. 
I'll gladly trade more weight and lower efficiency for quiet.
