I can recommend you many mices but first of all you must say if you have big or small hands and say how you hold your mouse, if it's fingertip / claw / palm grip.
But I will name a few:
For right handed with small hand you can't go wrong with Roccat kone pure military (it usually goes on sale at Newegg for something like 25)
Mionix Castor
Logitech g502 (it's a heavy mouse but has one of the best sensors)
Logitech g303 (same sensor of g502 but for small hands, it's very light, 90g)
If you can find a Microsoft intellimouse explorer 3.0 get it (doesn't matter if it's new or used) it has the best sensor if you don't mind use 400dpi (it's not possible change dpi's in this mouse)
If do not have money problems maybe get the new logitech g900 (same sensor g502/g303) and it performs amazing wired and wireless (it can be used in both ways) but it costs 150
Zowie's are great mices too with a grat sensor and driverless (you not will need to install anything at your PC to use the mouse with all the features)
But if you want a more precise recommendation post your hand size and grip style!
