Probably not up everyone's alley, but there is a new Kickstarter for a 3D-printed panorama camera. The image size will be X-Pan dimensions, not masked. I will not do the project justice by summarizing it all here, but you get to build it yourself which will certainly appeal to many and makes it very affordable. The cost could be a few hundred dollars, even with the lens.
