Re: What would you do?
My feeling is that the 7v7 will be worth its current 'new' asking price in a few years, like the VSBL that has risen a lot from its sub $1000 blow out prices. At their current price they likely wont sell too many, so it will be scarce, etc. So its a good guitar, and if you keep it 10 years it could be worth more than you paid for it, but who knows.
That said, you wouldn't have to look to hard to get another used (Japanese) Jem and a used UV777BK for less than the new price of a 7v7, but I would take the 7v7 over a Jem70/UV70 combo 100 times out of 100, no question. With all those bolt on trem guitars you already have, I would honestly look for an old ('78-'80) AR-300/2619 and a Lo-Pro UV777Bk before any of the other choices (and that would also likely leave hundreds in your wallet), just to round out the stable, but you are in a no lose situation here.
