Hello there, I'm a long time PC gamer, and recently I'm just offered a used Xbox360 at like $150, and the manufacture date is like around "Sept 2009". The only thing which is modified on that console is the "LT 3.0" which, in my limited knowledge, means that I could play backup-ed or downloaded discs. From your expertise in these Xboxes, is it worth getting? Or I would just go and grab a new, unmodded one at $200 (or the J-Tagged one at $270)? The newer ones in the shopping mall is with the "Slim" version, and I think all of them are with the Corona version. Thanks for your opinions.
