If you want something nice in your hand, you can always pick a pen you like and replace the ink barrel with a stylus refill.
Stylus Central used to carry a variety back when PDAs were popular, and I bet there are IR refills out there to be had. I've used my old Axim
Sensa stylus on my Readers. The tip gives very precise control.
But honestly I use that brush/rubber tipped cleaner tool more often. Because Cats.
