i wish i would've bought one of these first. instead, i bought a new one... and, i ended up sending it in for repair just to get a refurb, which was actually in mint condition, probably new.
Ive bought 2 of them, one 1gb one and one 2gb one. Work perfectly, look brand new.
Only weird thing was the 2gb one came out of the box in some weird language. I found the reset all settings and it took me back to the select language screen.
