I had an S2A and loved it. However the lack of parts and repairabililty finally made me switch over to Blads.
I have put many years, miles, tons of film and abuse on my Blads and have NEVER had to take them in for repair. I only CLA them about once every 4 years on top of that. I just don't have time for equipment that fails. If they were as unreliable as some people try and make it sound they would not have been adopted by the vast majority of professional shooters.
