I'm on the Wacom as well. From all the research I've read you're taking a bit of a chance on anything else. I don't have the latest and greatest version of PhotoShop but it works just fine with 7.0. As noted above it can be handier than a mouse on many occasions. I use it mostly with Painter IX where it really excels. Comes in handy for rendering those fictional British/Scottish superspies.
