I think I'm in the "go vintage" camp. Unless of course the deal is too good to pass up. No doubt they are very fine amps and you might get a couple nifty additional features: deep switch, soul control etc..in fact, I'm sure it's "nicer" than a vintage fender, but it will generally be harder to flip if that time ever comes. A vintage Fender on the other hand will slowly appreciate in value and you will always be able to move it if need be.
To give you an idea of what's out there, I just picked up this '64 transitional 6G2 Princeton for $1,100 out the door. Obviously, it's the penguin on the left. The thing had been serviced and the speaker reconed. It was good to go and it sounds great. Not to mention it's pretty damn clean.
