three years ago sounds right for a 760. This year its a different game. Companies now are flooding the market with fixies and SS bikes with all sorts of "flair" at $350 and under. Despite being possibly heavy and dead feeling these bikes are "new" and "cooler" than a high quality frame converted. This is knocking out the competition for vintage frames and driving prices down.
I picked up one of these new versions for a song and it is 26 or so lb! Why anyone would choose this over a nice vintage frame you can build to under 20lb is beyond me! It's getting flipped this weekend.
I rode it on my commute several days and the final decision is the brakes suck, it is heavy for no reason, if I want an SS I'll just not shift, and while it looks nice the geometry is odd and just strikes me as a markting built bike as opposed to a purpose built bike.
