Trackballs are 100 times better then mice.

No one who uses a trackball will ever go back to a mouse.

I have the best trackball ever (well for under $100) available for sale (but as said it only has 4 buttons):

There is a reason it sells for more then it did new now.

Ill let mine go for $80 and that includes shipping.
