Logitech G110 is a little expensive as the sum you provided, it runs smoothly anyhow when i test the responsivenee as quick as i could, also bring some noise in midnight, but it is unavoidable,right? the sound is acceptable can also be sure, the feature i like is refered to its Hi-Speed USB 2.0 hub port on his body and some kinds of color to choose. i found it could be cut down to be $49.9 in ebay.
but if you are not regard the brand as important, i may recommend this one for you, it is 45%off for $16.33 but will expired in next 8 hours. http://www.tmart.com/AK601-Mini-Wireless-Keyboard-with-Laser-Pointer_p121337.html
