THIS guy is selling G27 shifters for a lump sum. you would still need
THIS adapter, but together it would cost more than a FF joystick.
if you still want to go the FFshifter route, I have a Logitech Wingman Force 3D (missing the knob, because I used it as a shifter, but later moved the shift knob to a new FFshifter
so you just need some sort of shifter knob to attach to it) and a Logitech Wingman Strike Force 3D (updated version of the force 3d) in the box for sale if the price is right. Just make me an offer for either one
