Any good mice you could recommend? I used to use a Razer Naga during my MMO days and I've really missed the side button array, but I found myself replacing them way too often (they'd wear out and start double clicking in just 6 months on average).
The Logitech MX series is pretty decent, though I've had to start fighting with uneven mousewheel acceleration. Corsair makes decent mice, and Razer as well.
The double click issue I've had happen with a couple of products. A Razer opto-mechanical keyboard had this crop up, a previous Logitech MMO mouse did this (double left click as well), and even a "Topre" switch keyboard had this happen. I haven't had it happen with cherry switch keyboards (yet), but I'm sure it will.
It almost seems like an industry-wide problem that combines less-expensive switch components and debouncing tolerances that are set too tightly - it's like none of the newer products are set up to handle aging switches. Just a guess though.
