Presumably, since its been out less than six months, any broken ones would have been repaired under guarantee already, so I can't see there being any around, sorry. I suspect you're going to have to give it a year or so.
(or wait until unbroken ones get stupidly cheap, ala Dreamcast!)
*sigh* that's what I figured. Heck, the 1 broken one on eBay is already selling for $150+. At that price, I'll just pay another $75 for a working refurb under warranty!
