Once upon a time that was that was the normal street price. By once upon a time, I mean for the past 5+ years until January. It did spike up again when HD800 came out, then settled back down, but now they have their MAP enforcement, which is utterly stupid on many levels. However, whether they'll relax pricing again is unknown. Since the HD700 just came out they could be doing the same temporary elevation they did when HD800 was released. Or not. We'll see.
I'm sure from some ebay dealer you could find them...they'd be gray market, no warranty etc. But when was the last time anyone heard of a 650 failing due to defect? But the MAP enforcement has bumped even gray market pricing up.
