Title: Get One If You Can Find It!
Review: This and its brother (Model 64214), are my all time favorite track balls. I use these on Mac's all day every day for video editing, design, basic office work, gaming, and well everything! Although they dont have the smooth glide of the newest model, I prefer these because you can replace the light plastic ball with a heavy pool ball (I use an eight ball from a pool table) and the action is perfect:) Others must agree as I saw a used on on ebay go for close to $200!!!!
