I use several AGFA/Ansco folding cameras, all of which I have refurbished myself. While not easy to work on, someone with reasonable skills could probably fix one. Worst thing, as many mentioned, is the focus often being frozen.
I have been lucky enough to find NOS (New - Old Stock) bellows on EBAY through a couple sellers. On pre-WWII cameras, some of the leather bellows can be repaired using a combination of T-Shirt (screen printing) ink and sunlight curing. My oldest 1937 AGFA Jsolette (6x4.5 and 6x6) has a repaired leather bellows, which has worked great for the last four years. My larger 6x9 cameras all have replacement NOS bellows.
One thing I added was an accessory rangefinder. I found several Präzisz rangefinders after many separate searches through EBAY, and they have been reliable, easy to calibrate, and easy to use. The downside is that they might run more than an AGFA folder.
I almost exclusively use transparency films in my folder cameras. The results from an old uncoated triplet lens are quite amazing. I have a few of the hard to find lens hoods for my old folder cameras, though I don't know if that really helps much. One thing to avoid is shooting into the sun, since flare can be a huge issue.
My suggestion is to get two of whatever you want to take along. Basically either load a different film in each, or use one as a backup camera for the other. Maybe one has a flash sync post, and the other might not, which is another way to do this.
Be careful to open and close these folder cameras slowly. If you let it spring open with film in it (especially on a 6x9) the bellows suction can actually pull the film slightly into the rails area, which ruins film flatness. When closing the camera, make sure that nothing is snagged or blocked, which can help avoid damaging a shutter release arm, or damaging the folding parts. These are very strong cameras, but you don't want to force anything.
