The front wipers, which are going to wear out way quicker than the rear blade, are a standard design and can be bought anywhere. The rear wiper blade attaches in a somewhat unorthodox way - thus the need to buy the blade insert from the dealer. Since the rear blade is something most people (like me) replace very rarely, the relatively high ($20) cost and need to get it at a dealer isn't a big deal.
As for the actual replacing, there is NO need to go to the dealer. Just follow the instructions that come with the insert. It's really very simple, especially after you do it the first time.
I have heard of people being totally confused by the instructions and/or who couldn't remove the single nut holding the rear wiper assembly on the car. I think one of them actually figured out how to just replace the rubber part of the insert without taking anything off the car.
Maybe someone else who has found a replacement rear blade from someplace other than the dealer, or has figured out another way to replace it could chime in.
