I'm actually buying one of these within the next 24 hours, but at that price isn't worth the huge risk of buying in this venue + losing all my money. I found a new 32gb for $476 shipped and you can just add on extra memory. I could go on but you have to better to tip risk vs reward ratio here.
FYI, I didn't read the large blurb of text maybe this includes a bunch of freebies and you've got a way to guarantee device is like you say it is.
