If you're in the market for an R6 there are several potential good deals floating around in MD
$3500 for an '05

$4500 for an '07

typically I don't see any supersports below $5000 unless there's something glaringly wrong with them.
There's also this guy trying to sell 3 bikes at reasonable cost though his taste in bikes screams hooligan.

There is nothing on the price level as the OP though, those are just impressive. I'd invest in a few and make some travel money over the summer.
