What do you use for a mouse or trackball etc? What mouse do you recommend?

I use primary keyboard commands as much as possible, including 'shift + F10' for right clicking. Of course a mouse is pretty necessary when working in photoshop for moving windows around and such, but I still use a lot of commands there too. You'd be surprised how quickly you can duplicate two layers, add a layer mask, apply image and add an adjustment setting using the keyboard, I'm not a fan of using the mouse. Also if you saw me working you would ask if I'm left handed, I'm not, but I use my left hand for mouse (just thought I'd add that).

Not certain which mouse I have installed, but I do like the feature of having the push buttons on both side for back a page and forward a page.

PS: Strictly track pad and keyboard commands on laptop too, the tab key is a beautiful thing, not to mention the directional keys.
