Just picked up a Logitech M950 performance wireless mouse for a ridiculous $58 (check out Logitech's massive sale if you haven't already). I think ye olde G5 will be relegated to be the work mouse.
Ooh!
Cheers for the tip DD, I'm in dire need of a new Keyboard as I'm using this dinky ALDI thing because my Original G15 (Blue) Keyboard died earlier this year after many, many years of abuse.
