If you are a member of the ARRL, there was a shootout of sorts on switching 
supplies just a few months ago.  All will have a little noise, but a lot of the 
models in the article had a pot to adjust/move the noise if it interfered with 
one of the radios you are using.

I use Ten-Tecs switcher supplies, but they are usually an OEM device with their 
name on them.  Astron and Chinese manufacturers.  None that I own have the 
ability to move the noise a we bit.  However, they work fine for me.
