Large, multi-button mouse recommendations?

Forget mice -- get a good, large track ball. I use an 2.25" Atari arcade trackball that I put in a custom cardboard and foamcore case, with two arcade button switches. I got it from Happ Controls (http://www.happcontrols.com/). Current price with USB or PS2 interface is $145. When I got mine (almost 15 years ago, so it is on-topic), it did not come with a PC interface, so I cannibalized a cheap serial mouse and made an interface. I think I still have plans I made up for that. I have had to clean and lube it only once in >10 years. I have it hooked to an IBM T20 laptop -- in its box, it's nearly as big as the laptop! -----Original Message----- From: Bill Richman [mailto:bill@timeguy.com] Sent: Friday, February 28, 2003 8:28 AM To: cctalk(a)classiccmp.org Subject: OT: Large, multi-button mouse recommendations? 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.
