Guy,
Stitcher is at;

When I bought the software, it ran around $450.00 (US). The learning curve is difficult (but fun). You also need a \"spherical elevation bracket\". It goes on the head of your tripod for exact calculated measurements of the camera. Some people do it without the bracket. The bracket ran me about an additional $400 or $500.00
They have samples on the site, and the forums. Or click on www by my name and see some more.
I should be using it more than I am at the moment. It has good value for stitching \"flat\" i.e spherical. The QTVR 360's never really caught on, hence I stick with the work that pays. Stills.
