The $20 ones look nothing like the orignal. They have a black plastic base which allows them to be adjusted so that you can have them be straight up no matter what the fender surface is, more of a universal fit. The expensive ones have the correct bezel and look as compared to stock. I just bought one of the more expensive ones off e-bay, $85 + 10 S&H. He normally sells them for 105 + S&H (buy it now) so since this one was an auction starting at $85 I took a shot. I will post an update once I recive it.
I went with the telescoping since I have an AM only car.... Thanks for all the input.
