cheap wireless PC controller?Follow

Guess this also could have been posted in PC repair but it is for Video games. Anyways I have been looking and have found several different PS2/Ps3 clone controllers that are wireless for PC. Unfortunate for me most of them have said they are not compatible with Windows 7 64-bit OS (which is what I use). So anybody recommend a cheap wireless controller? I have an old PC controller that is USB but its not wireless and it basically looks like a PS1 controller without the Analog sticks.
