I have used a VS-35M with a PRO, PRO2, and a Kachina. Flawless with
all. Can be noisy with mechanical hum, so you might want to locate it
away from the rig, mic, etc.
I got an Icom PS-125 switcher free with my recent PRO2 purchase and it
appears to have no faults. Very light, quiet acoustically and
electrically, and run very cool. Rated for 25 amps.
