What sold me on the 500cm system in 1995 (here in the USA) was when I went to check out the "electric Rollei" system, the dealer didn't even have a battery charged to demonstrate it for me. He talked about it, but I couldn't put it through it's paces. I went to another dealer and bought the uber-reliable 500 and 3 lenses. I also did contemplate the (less expensive) RZ system. It was too big for my needs and didn't feel as robust as the metal 500. Some 20 years onward, just one failed lens shutter (last year- the 80mm) and a couple clean and lubes.
