Bought mine at Rockauto.com, around 70 USD when i remember well. Easy to change. Its just one c-clip and with a puller you just pull it off the axle. The new one you just tap in place with the right size of socket on the center part.
Perfect! There's a place not to far from here that focuses on drivetrains and should have the part for a good price.
