Yes I have, but I guess it depends on how handy you are and how much has to be done. The chrome on the arms and bases was coming off of mine and I found a good deal on a pair with cameras in them. Naturally the wiring for adjusting the mirrors was completely different so it took longer to get that figured out and converted than mounting the new mirrors.
Several of the mounting holes were rotted out so I had to drill them out bigger and epoxy 1/4" nuts in the bigger holes. The camera wiring has simple as the four wires were all in one cable and buying a compatible monitor, it was plug and play.
