I bought an R9 just to give it a shot a few months back. On the plus side, great viewfinder. Stress great. I also like the general look of the camera.
On the downside the lug placement is terrible for me and the reach to the shutter button is unusually long. I'd recommend the motor drive for the accessory shutter release and grip.
I frankly prefer my F6 for a film SLR, an incredible machine. Lens selection obviously can be a determinant as to whether it's for you or not.
