Lan party questions

I have in my home 4 xbox's and 3 360's all wired together. I have had a couple of lan partys but we are growing tired of Halo and Halo2. I'm wondering if anyone has some suggestions for some good lan party games. I'm looking at mechassault for one of the games but is there any other cheap lan party games that work well? Also how much luck do you have buying games from ebgames.com that contain the box and instructions. I guess they also done give free shipping any more. Thanks for any help.

Are two I can readily think of and are cheap

any other suggstions?

Star Wars Battlefront is getting cheaper. Crimson Skies would be another that is good and cheap.
