Per my previous post, I prefer the FA-VA5 as well ... and it is about
half the cost of the Rig Expert.
One of it's nice features is the 5-band SWR display for checking which
coax lines go to which antenna. I obviously don't have to use that very
often, but when I'm changing things around it can be pretty handy.
