Had an M8.2 which was a great camera, but didn't like the lens multiplying factor. I see the world in 28, 50, 90 but I couldn't do that with three lenses if I brought a film body and the M8.2 digital body. So I sold it for an M-E, which I really like.
But most folks I know still think the B&W conversion of M8 images look more like B&W film than the converted images from the M9 series cameras. I think that might be one reason the M8 cameras are still holding their value.
