Keyboard: Matias Tactical Pro 3. Not quiet, but good.
Mouse: Kensington Optical Elite. My last computer upgrade killed the MouseWorks driver software, so I'm using USB Overdrive. Still have a few more in boxes, so I'm looking for a new mouse for after I run out.
Game Pad: Logitech G13. I had a Belkin Nostromo n52 which I loved, but no driver software means I had to switch. I didn't like the driver software Razer wrote for the n52te, so trying the Logitech out. It has more buttons, which I like. Even though the analog stick can be pushed down for a fifth click I preferred the d-pad on the n52. I like the driver software.
