I've been doing a lot of finicky CAD work recently, and my hand is really
starting to hurt from gripping the mouse tightly for fine control. I'm
looking for a larger mouse (according to one site that sells various sizes
of mouse, I'm between a "large" and an "x-large" hand size) that I
can lay
my hand more or less flat on top of (maybe with a couple of finger loops,
so you don't have to grasp it constantly) and ideally with a small
multi-button keypad of some kind on top. Is there such an animal out
there (aside from the Space Mouse guys' $500 products) that might have
these features? Suggestions welcome.
