a set that vibrate furiously at highway speeds

 

Matt,
If you talking about the ebay mirrors vibrating when they are up-right or vertical i agree. I have a set off ebay that i paid 220 for and at highway speeds no way could you use them up-right, but i always have mine horizontal and they don't vibrate at all so i guess just know what you're getting yourself into before you buy.

 

Is there a set that's better then the other? OEM vs aftermarket?

 

OEM is best here. One of the few cases
