That narrows it down quite a bit.anything but green led. macro keys arent needed but dedicated media controls are nice to have. numpad yes and brown or black preferably.
i think the 710 uses brown switches.
Sounds like the Logitech 710 is the winner, but runs about $160. The K90 meets all your requirements except it has red keys but can be had for $120.
I think that's it for media controls, though several others have "function" media controls. The normal razer blackwidow and Mionix Ziabal 60 are nice but are backlit green. The razer blackwidow BF3 version is backlit orange if you don't mind the BF3 scheme.
The CM storm quickfire pro looks interesting, but is only partially backlit.
