What kind of keyboard and mouse do all you web developers feel most comfortable on?

I use a standard keyboard.. wired at home but wireless at work. I use a wireLESS trackball - the kind with the smaller ball under the thumb and 2 buttons with a scrollwheel between them (logitech). I prefer the control that the trackball gives me when I'm designing in Photoshop.

If you want to buy the keyboard than the TVS company will be more preferable to you because they are long-lasting and its switches are working very good and for mouse i will suggest you the logitech company.
