Logitech MX 5500 mouse/keyboard combo
from pictures on the internet, the mouse doesnt look very big, but it really is.
The keyboard is bigger as well.
it's like they took a normal logitech keyboard/mouse combo, and made it 20% bigger
I'm a tall guy with bigger than normal hands, and I have two of these setups. one at home, one at work
as always, logitech stuff lasts forever. htey're out of production, but perhaps ebay?
