I don't know if sturdy is the correct term. My RAT7 just went out, lookin into a new one for <$70 USD. I really liked how sturdy, if not just "heavy" it felt, but dont want to shell out another $100+ on a new one. I dig the Corsair ones and some of the Logitech ones, some are too small tho. Regular size is prefered. I've never been a fan of Razer tho. Also, don't really need an MMO mouse with like 10 extra buttons, tho 2-3 extras wouldn't be too bad.
Appreciate your advice!
