[amsat-bb] Yaesu 847 power supply -linear vs. switching

I purchased a Yaesu 847 for both satellite and HF work.  Since this is my 1st base-style transceiver I am now in need of a power supply.  I was originally considering the Astron RS35M and am curious if linear or  switching is the proper choice?  Is there a Amsat BB favorite between switching and linear?

Thanks for any help!
