It's not a matter of price, it's a matter of safety and asthetics. If it looks the same as the drivers side mirror I currently and it provides a better field of view I'll buy it. If it looks almost the same, I'll think about it and if it looks like the passenger side mirror on my dads motorhome, forget it. I don't have vibration problems with my current mirrors, so that is not a concern.
If there is anyone who has ever seen one of these or has one, I'd like to hear from you.
