Hi, I am in the market for a new mouse. I would like a two button mouse that scrolls horizontally and vertically like the mighty mouse. I owned a mighty mouse in the past, and liked it. However, it didn't last too long and broke :-( I have since been attached to a two-button mouse, but it only vertical scrolls. Can anyone recommend me a good 4 way scrolling mouse? I would like one similar to the mighty mouse movement, and not two separate button scrolls (one for horizontal , one for vertical) like I have seen. Thanks!
