I have a second-hand Corsair K95 Vengeance (Cherry MX Red), with half of the LED's not working. I don't mind the fact that the lights aren't working and I don't like the MX Red switches, however I really like the keyboard. Especially the media keys/volume wheel.
My Mouse is a Steelseries Rival (pre-100/300), because I find it's much better suited to my larger hands.
My headset is a Wired Nemesis Akuma - I believe the quality is excellent for the fact that it cost £15, however an upgrade would be perfect.
My mousepad is a generic one which cost like, £1 on ebay.
I am ever so slowly gathering new upgrades to my setup - currently deciding whether to save for a second monitor or a new headset.
