At my new job I've been placed in a beautiful gray cubical with not one, but two mighty (mice)? Both featuring track wheels that do not work(one only goes to the right)-I've tried cleaning the things-they're spent. So, I'm looking for a replacement. I have a wacom intuos tablet that I use for freelance on my mbp, but i'm looking for a standalone mouse for mostly layout work in quark and indesign on my work G5. I'm looking for advice from designers/pro mac users on a durable, lasting replacement(with a wheel!). Thank you in advance.
