I'm using this - it comes with two stylus. Primary reason for buying it was because it retracted so you could take it around with you without damaging the head. Very nice and much better than those with a rubber head.

Thanks for the advice. I just ordered the carbon fiber MoKo, along with these styli. Writing with a finger is awkward, and I don't like having fingerprints on the screen, even if it is the intended use.
