<DIV><BR></DIV>Well, I took the plunge and ordered a new VS-70M from Universal
Radio, along with a powerpole plug strip and some extra connectors. I plan on
reselling the VS-50M and a 21 amp linear to recoup costs. I don't think I'd
sell it to anyone on the list though because I've had issues with both of
them.<BR><BR>
