ah, screw razor, get the latest in the Logitech G series, had mine for like 3 years now (the old G15 with the lcd-screen that you could fold down) and its still great, nvm the razor double hitkeys sensitivity, mine had like 36 quickkeys on the side all programable (12 * 3), and a good lcd monitor on top, I usually uses it for vent monitoring but there is loads of apps for it out there (including css stats).
This one also got the usb ports (2).
The newer G15 one got fewer quickbuttons but looks quite imense aswell.

but Id go for the G19 for sure.
