Not sure about prices (Wangled mine under warranty even though the car was about 7 years old!)... Best looking on ebay could get a decent used one. Just looked found a used one for £74.99 and a scabby whitewormed one for £39
Don't think there that much new, but I stand to be corrected...
Open tailgate, remove trim, remove rear wiper motor, remove the 3 screws out old handle and jobs a good un!!!
