Illuminated keyboard with standard key layout + media keys
a. Has the standard layout with \ above enter, backspace above that, 12 f-keys, numpad, etc. - Logitech mk710 is my work keyboard and I like it.
b. Has vol up/down/mute and play/pause on the keyboard
c. Is backlit.
d. Is reasonably quiet - don't want to be all clack clack buckling spring
e. Is pretty cheap.
I can find sub-25$ keyboards that look like they'll work EXCEPT that the key layout is wrong, and the K800 would be great - except its north of $80 on a good day.
