I've got a CM Storm Trigger keyboard for trade, that does
most of what you've specified. Macro keys on the left (five of them...), red LED backlighting (multiple modes, if you care about that kind of thing), and it's definitely aimed at the gaming market. Oh, and it has Cherry MX Green switches.
Small? Not so much. It's a full-size board, attaching the stock wrist rest makes it wide AND tall. But three out of four criteria ain't bad! If you've got something to trade, let's chat.
