Starting my boyfriends christmas shopping already... HELP!!!?

Okay, so its about time I start my christmas shopping.. Iv already decided on a 400 flatscreen tv, and my plan is to already have his tv set up christmas morning.. And using the big box to put a bunch of smaller gifts inside.. And my problem is that I can't really think of anything to get him.. Besides the tradition of underwear lol. I'm thinkin a hard drive for his xbox.. And I need help with some more ideas.. He loves video games (xbox 360), burning cd's, his suzuki LTZ 400 four wheeler, his 1979 pontiac firebird, kid rock, johnny cash, he doesn't dress up, so name brand clothes are a big no! Ugh!! Men are so difficult :( ideas would be greatly appreciated!!!
