Searching for the GigaVac GH1 relay, I found that Henry Radio has the 26VDC 
GH3 version of the GH1 for only USD $39.95.

Apparently the GH3 is load-switch rated, and supposedly able to withstand 
accidental hot-switching events better than the GH1, Jennings RJ1, and 
Kilovac counterparts.  GH3 open & close switch times are comparable with the 
GH1.

Anyone have experience wit the GH3?   Do they switch as quietly as the GH1? 
At USD $40 ea. for the 26VDC version, that's quite a value.
