What Determined said.
Here's a few decent affordable alternatives:
Gigabyte GM-M6900
Anker High Precision
Sharkoon Fireglider
Sharkoon Drakonia
Razer, Mad Catz, Steelseries & Roccat are usually quite overpriced. And man, functionality over design.
Personally I love Roccat's Kone+ and Mionix' NAOS 8200, but I didn't wanna waste that much for a new mouse and went with the Anker one from above instead. Best would probably be if you visit a local hardware shop and get hands on to see what feels best for you.
