I use a Rotring Data Quattro pen which includes a stylus. I bought one a few years ago when I had a Palm. There are a few different designs available if you look hard enough. The original looked quite functional, the more recent ones have a bit more "style" to them. It's a bit difficult to find a good picture of it on the web; this is quite a good example. http://www.penshop.cz/DetailPage.asp?DPG=4726 You sometimes see cheap imitations for sale elsewhere too (which aren't so well built but do the job until they break).
