i've always liked the deathadder's shape since i prefer large mice in a semi-palm grip. i prefer the older rubberized models though some people do like the newer ones.
another nice larger mouse are the roccat kone and clones.
if you do not mind slightly narrow mice the logitech g502 is a nice mouse and if you score a deal can be had for $55 though it normally goes for much more. i had one and it was very nice though i do not like hyperscroll wheels (some do) and i found it a bit too narrow for my tastes.
