Thanks Grecco, it arrived today and I've got my 1000 pts. Worked out very nicely for me b/c my 360 RROD'd on me recently (first time) and I got it back in the mail today along with Avatar. Very nice! And props to whoever threw in the OXM demo disc with the free Rock Band tracks on it. I'm psyched to try them out.
Despite all of the talk it still surprised me how incredibly easy those achievements were.
Jgel, send me your mailing address so I can get this out to you.
