I would second the Herron recommendation. There is a VTSP-3A (R02) that just came on today. Grab that and then call Keith to pick up a matching VTPH-2A--I think you will be happy :>). BTW, I've owned a bunch of ARC equipment over the years (not the models your are considering) and they didn't hold a candle to the Herron gear. Good luck!
PS: Cool system!
