I have a mod chip on my xbox. It was really easy to install. The great thing about the mod chip is that it lets you swap out the hard drive, so I put in a 120GB HD. You can go to Blockbuster and rent a game and then store the whole game, which is usually between 1-2 GB, and play it whenever. I have about 10 games stored right now. You can also burn games to DVD if you d/l off the internet, but in order for it to load quickly you must use a DVD burner/DVDR/RW. I ordered one and am waiting for it right now. The prices have went down. I found a DVD burner for $230 and the DVDRs for 50 cents a piece.
