Jim,the Russian panoramic cameras,I've got a horizon s3 u500 are great value for the money(200-300 dollars)Shutter speeds on mine are 1/2,1/4,1/8,1/60,1/125,1/250,1/500.aperture 2.8-16.I believe these cameras have more shutter speeds than the widelux.I bought mine to see if I would like the panoramic format and I love the camera and it didn't break the bank.I've got a few shots in my gallery from this particular camera.I can't comment on the quality of the widelux but the horizon is good quality especially good at f8 and higher.
Ditto on the Horizon. Mine lay dormant for a few years, but in the last few months I have put several rolls through it. Good, sharp lens. Advisory: keep it level!
