If you really don’t want to touch your screen, the elago Stylus Hexa is very nice. (Ignore that it says, “for iPhone”; it’s for any touchscreen.)

I have one and I really it. It has a great weight/feel to it.

PS: I tried linking to it, but automod deleted my comment, so this comment doesn’t have a link. Sorry, you gotta search. Guess those are the rules. :-/
