I was looking around on the giant wall of donated computing accessories at my school's computer hardware club room, and I found not one but two USB Sun Crossbow mice. Tested 'em and they both work. They're absolute beauties to use, feel great, and the clicking is has a nice 'feel' to it. They're in new condition(they were in resealable plastic bags) and I get to keep one(the other goes to one of the C.H. computers I use)
