After close to a decade of excellent service, my mouse is making its last hurrah; it's long since lost those little skid pads from the bottom, and now the cable has a break in it. Ideally I need a wireless mouse with more than the basic assortment of buttons, but I can't go on with the brand I'm used to as their support for Macs has gone from bad to non-existent. This means an expensive shift to Logitech is required, and that is more than I can afford right now...
