Hello! So I have been looking around on craigslist for an upgrade from my LG Thrive. I came across this R2-D2 Droid, and thought it looked really cool, and seemed to have better specs than my LG Thrive. At least I think so, haven't compared them side to side but I would assume so. I'm just wondering if buying one of these used is an ok idea, or if it'll be a bad idea because of quality issues. Thanks!
