I have a bit of a weird setup that I've accumulated over the years. In my most recent attempt at breaking into Linux, this was my main barrier. In particular, I use a Corsair keyboard, a Razer Naga X mouse, and a Logitech Extreme 3D Pro joystick. As it turns out, the mouse, and seemingly the other two, aren't compatible with Linux.

I don't have the money for replacements at the moment, but when I do, what brands/products should I be looking for, for similar functionality? I can give up some features, but essential to me is the ability to set up keyboard macros, and an MMO mouse with the ability to toggle DPI via the side buttons.
