Not sure if anyone has one for sale. I just picked up a TurboExpress, but the back housing has some annoying scratches and white stress marks in the bottom corner of the system on the back housing. Looks like it fell and hit some concrete some point in its life. The front shell, battery cover, and everything else is fine. Just the back shell could be replaced to kick up its condition a notch. It's also missing the rope like wrist strap if anyone has a spare one of those for sale.
Thanks everyone!
