Hi Catherine, I have used a Logitech Marble Mouse in win 98Se for 2 years now and love it. I recommend it over any of the other track balls. I do prefer the Logitech optical mouse over all of them though, no cleaning required. Mike ~ It is a good day if I learned something new.

I have experience from many years ago with a Mouseman that had a thumb ball which I found very stressing on my hand. I'd like to purchase a trackball with a larger ball in the center like the Kensington or Logitech Marble Mouse (which is really a trackball). Does anyone have experience with these, or others, that they would share or give some buying advice? Some of the web opinions I've read indicates people who've used both the Kensington Expert Pro's prefer the older, plain 4 button, which can still be found, I'm just not sure the $60 price difference between that and most others would really be worth it.
