Yes they are hard to find, but not impossible. I think if I were starting out with this again I would get a GW69011 or 111 AND a GSW69011 or 111. That gives you a 65mm and a 90mm. Maybe substitute the GW690 for a 670 to give you a better crop for portrait and more shots per roll. I started with a GSW690111 and got beautiful results.
What is doesn't give you is the brilliant 50mm and the 150 and 180mm. available for the G range, but these are expensive and even harder to find.
Also the GW's are newer cameras and less likely to give you mechanical headaches.
Hope this helps.
oh and the GWs have EBC lens coatings for better contrast and flare reduction
I know the film counter can be reset or fiddled, and the problem started with the GW690 in 1978. I also know the GW690II has a good rangefinder spot, hopefully making it easier to focus than the GW690III.
Looks like a beauty to me at the right price. The important thing about these cameras is that they are mechanical and fairly simple, so that even an old beaten up one can be repaired and serviced for as long as there are service people out there to do it.
Now get a matching GSW and you have an outfit to cover most photographic tasks.
Here's an image from my GL690 with 65mm. http://www.flickr.com/photos/john_mayger/4525226587/
I have a mint (less then 50 shots) GSW690II & a nice used GW690III.
While the GSW is nice, I enjoy the GW because the easier focus and brighter RF. And the III is easier to load then the II.
But then again, if I'm shooting the GSW, I'm usually at infinity and on a tripod.
I love these cameras so much that I am currently looking for another set. I want to have two of each, but different model numbers.
6x9 > you
And yet the camera doesn't make a photographer any more photographically worthy. 6x9 is a nice format certainly, and I wouldn't mind having one, but 135 is also quite good.
