Rear Right Tailight needed for 2006

I am in need for a rear right tailight assembly at a reasonable cost. I tried the dealership and they were going to rob me of $204 for one. Can I get one somewhere else? I've checked Ebay and they didn't have one for me. The dealership told me there are two different types of lights for this year that I have (2006) My vehicle was manufactured in May or June of 2006 I think. Can somebody help me out on this issue? PS: I was loading camera equipment into my Prius when I swung around a lightstand too quickly and it hit the light knocking a quarter size chunk of plastic out of the middle of it. Also, can somebody explain how to remove the light assembly? Thanks Dean
