Teche TE720 (previously called the Teche T2) and TE720 Pro are almost spherical 360-degree cameras with high resolution photos. We now have some additional info, including some sample photos.
First of all, Teche has two models - the TE720 and TE720 Pro. The entry-level model, the TE720, has 96 total megapixels (16 megapixels x 6 sensors) and is $2499.
The TE720 Pro has 72 total megapixels (12 megapixels x 6 sensors), is a little more compact, and is made for "harsh environments." The price is not stated on the website.
