At one point, I had all 3 variants of this cult classic. There's really no difference between the original R-D1 and the R-D1s after the firmware upgrade. Eventually, I parted with the first 2 and kept the R-D1x, in favor of the ability to use SDHC cards as well the non-articulating screen. I really enjoy the fact that all the key shooting parameters can be set on the camera without turning it on.
Thi model is officially discontinue and original Epson batteries are now no longer available at most retailers. What are you guys doing for replacement batteries?
Cheers,
