I managed to get a black one on eBay for $400, which is in fact the lowest I've seen since I started watching. I have to say it matches the sensitivity and timbre of the Fortes very well. I'm quite happy with it. But would I have spent more? Not without trying something like an RC center (or a pair of Heresys) first.
Unfortunately, the demand on eBay is going to drive up the price elsewhere. (BTW, note that the winning bidder bid *over* $635 yesterday and stood up to all the last-minute snipe attempts today. Your $700 bid might not have won!)
So given that they command this much $$, why isn't Klipsch making them? I'd love to switch to Oak for $400.
