Im looking to buy a shift knob that has a good feel and isn't too expensive. I was looking at buying either the Cobb shift knob or Kartboy knob. Anyone have any experience with these or any other good shift knobs? Also, is this STi shift knob on eBay legit? $20 seems pretty cheap...JDM Subaru WRX Impreza STi 5MT Shift Knob GC8 GDB GRB | eBay
