SolarisLunaris: Logitech G600 are great !!!
It has many buttons, fair price, and durable build
http://gaming.logitech.com/en-us/product/g600-mmo-gaming-mouse Got that myself. Yeah, good mouse - but one heck of a learning curve.
Namely b/c the mouse is big and wide, so your hand is gonna have to get used to that. And your hand's also gonna have to get used to the 12 or so buttons on the left side of the mouse itself. Like I said, that can be a heck of a learning curve - but if you get over the hump of that curve, it can be super-rewarding; especially in MMO-style RPG's.
I have a lot of different Logitech mice - and I like the G300S. I like the ambidextrous buttons on the top of the mice on both sides. I wish more mice had buttons like these on the top of each side of the mouse.
If Logitech would combine the top of the G300S and the left-side of say G502 w/ those few buttons there, I'd probably be in Logitech Mouse Heaven.
