My old MicroSoft Intelligmouse died. The last one died also and so I had bought this one because I like a BIG mouse. But now I thought I would try something else so I paid $100 for a Logitech MX Revolution. It seems pretty slick but it doesn't seem to match my hands. I see that I put just my fingertips on the mouse it seems--I don't put my whole hand on and so I click more on the top and less in the front.

The MS mouse is easy to click on top, but the Logitech is made for clicking more in the front. It's also anyway I think harder to click than the MS.

Any suggestions of a good mouse? I need it pretty big ( the MS is almost 5 inches long ) and easy to click on top.

Thanks!
