Indeed - there are plenty of cheap enough options for a 67 camera with good optics, but it's the sheer pocketability of this one that gives it its appeal. The Mamiya 6 is another possible alternative, albeit a smaller frame, but even that isn't quite slim enough to just slip into a coat pocket. In the end the Plaubel is the only one I can think of that's really comparable. Now that did have a wide option - the 67W, which IIRC had a 55mm Nikkor. Not sure how good it would have been in the corners though unless very well stopped down - I wouldn't want to bet my house on it.
