I'm trying to find a good 8-20button mouse. What are your suggestions?

Hello!

I figured this might be the place to post this since I'm seeking a peripheral. (I realize cybermonday just passed but I'm going to wait for X-Mas sales.)

I'm looking for a gaming mouse that actually keybinds different buttons correctly. I tried the Razer Naga Hex and hated it- I found it to be clunky and the software didn't work. However I've found that to play games the way I want to, I need at least an 8button mouse. I've seen 20button MMO mice but I have no experience with them.

What are your suggestions? My budget is around $80-100 since I haven't had to buy a new mouse in about 7years.
