Good afternoon Alex Hawley,
There are plenty of AGFA/Ansco or similar Balda folding 6x9 cameras on the used market. While mostly front cell (lens element) focusing, the results can be quite good due to the large film area. Many of the later (post WWII) models had an accessory shoe for mounting an external rangefinder, which in practice is easy to guess focus.
The downside to front cell focus cameras, especially many of the AGFA models, is that the grease has dried up making the focus no longer movable. I have seen some where the owner thought is was focusing, but instead the entire front group was moving. This is not super tough to fix, but could take some time to do, and involves handling small parts.
I have a few of these already fixed up and in use. My idea was to get several bodies, then mix and match parts to get nicer versions. These are so low in initial cost compared to a Zeiss or Voigtländer folder that it is practical to own a few. The varieties are mostly number of shutter speeds, widest aperture, and in the rarer models more lens elements. There are also models with built-in rangefinder (not coupled to the lens), though they are approaching the prices of (potentially) better folder cameras.
I managed to get some NOS bellows for Kodak folders, and trimmed them to fit. So now I have three fully functional and operational folders. My favourite is actually a pre-WWII Jsolette that does 6x4.5 and 6x6, though it is somewhat rare and probably not worth the effort to try finding one, then restoring it.
I shoot colour transparency films in my folder cameras, just to give you an idea of what a restored or refurbished model is capable of achieving. The best shutters are the multi-speed Prontor or Compur variety, since they offer more speed choices than the simpler shutters; some of those include a flash sync post or even a self-timer mechanism.
It can help to add on a Präzisa rangefinder, or a similar model. Once you calibrate the accessory rangefinder to the front cell focus scale, then focus error is a rare event. A lens shade is another nice accessory, though these can be tough to find.
Best of luck in your search.
Ciao!
