Soooooooooooo . . . I ended up just going for the VT30. I have a Toshiba 55SV670u in our main room at >15' away in our looooooooooong narrow living room that I'll be swapping so the SV670 will be at the 8' viewing distance and the VT30 will be at the ~15' distance (couch is ~15' or more away, can't remember, the love seats on the sides are much closer which should be nicer for any gaming/3D experience).
As for details, you just call Amazon, tell them where the price match is, verify the model, and they enter the rest. When I called, they went through the procedure, came up with US Appliance's price, and then ran it through first at Amazon's normal price then adjusted it after the fact. Overall, it was ~10 minutes and the woman on the phone was very nice and easy to deal with. She even made sure I did not accidentally get two of them (my wife might have asked questions about that).
Anyway, thanks for the advice and the tip on the price.
Edit: FWIW, my total came to $2,497 shipped with their standard "FREE Super Saver Shipping."
