Actually, you can get some clothes, articles and other things for your avatar, but, only a few accesories works. You must search about: Modio, Le Fufflie, usb xtaf v32. Works in a non-jtag console. (But i thik you can be banned) Excuse me if you dont understand my poor english.

Im not really a bit fan of the avatar market place cause i think its a waste of microsoft points but ill download free stuff
I have never spent 1 ms point on avatar items, I have got some pretty good ones just from the free deals / unlocks in games. I do agree buying stuff is a waste.
lol, I haven't bought anything either. Btw, here's a link to a thread I helped create that has all currently free, and many once-free, avatar items http://www.xbox360achievements.org/forum/showthread.php?t=220994
