For those of you operating with a HTPC on your couch. What longer dist mouse/keyboard combo do you use. I was using a Targus 2.4ghz combo that worked ok, but the mouse recently broke. I am now using USB cord extenders for the time being (bluh). What should I be using? What have you had luck with? I want something with up to 30ft range as I am 15 or so feet away.
