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.
