I like small high-res mice. Sadly high-res are usually gamer mice which often means not small not wireless not cheap.
I used a r.a.t. m for a while, but the drivers suck. Now I got the Logitech G900 (got it for a lucky price), but it is biiig. Especially nice with it: you can map a lot of buttons (and a shift button for even more).
I really liked a few cheap dongle mice, but I break the keys to quickly on those.
If clicking hurts: map some keyboard key to the mouse button.
