That Hasselblad setup is one I have and would highly recommend. For years I had a 500CM, which I love, but which I've always found hard to hand hold and so I was always tethered to my tripod. Then a couple of years ago I was in a camera store and they had a great deal on a 503CW demo, and on an impulse, I bought it (I wish I still had the money to be that impulsive!) That winder makes all the difference. I can hold it like a 35mm camera (albeit, a heavy one), and that has freed me up to make pictures of people that are not so stagnant because it's off the tripod. I'd recommend it to anyone.
I also liked seeing the Nikon FM represented there. My first camera was my FM, which just celebrated it's 30th birthday and is still going strong. That camera changed the direction of my life.
I'm glad that film is so popular in Japan! One question though: What is an oba-san?
