Well it looks like there are several used phones available online. I think I can get both the Beyers and the Senns for under $200 used. Should be interesting. I can't wait.

P.S. Is Sennheiser about to release an upgrade to the HD650? Everyone seems to be blowing these out at under $300 (new). Considering what they were when they were newly released, it looks like there's something brewing.

One more thing: the Grado headphone amp won't cut it with these headphones. Any recommendations in the $200-ish price range, used; or is that just too low for a decent amp?
