You can get a new panoramic film camera for $69 - the Sprocket Rocket [1]. It makes images with grungy lomography charm - edges are soft but center is surprisingly sharp for a plastic lens. I really like the look of the images it produces. It has a hot shoe and a bulb setting.
While cool, there is quite a bit of difference between this and what the widelux is. The widelux rotates the lens as the front cover moves, which creates a drastically different look.
