Honestly what's the point in a better mouse? a mouse is a mouse, won't make much of a difference if you got a $5 or a $50 mouse.
Some older mouses get clogged up with crap inside that is too hard to get out, so the mouse ball stalls a lot. My friend gets all these weird mouses... One with a back and forward button on the side...And one with the mouse ball on top xD
Thinking about getting this'n.http://www.logitech.com/index.cfm/mice_pointers/mice/devices/163&cl=us,en

Secondly, those two aren't weird at all.
Get a mouse, groom it every day, don't forget to feed it. Have fun, and don't let it byte you.
