Ok.... New to this forum and the world of panos! I am about to invest in a pano head and just cannot sort out which pano head is best for me. I'm sure this has been covered, but couldn't find anything. Point me out if this has been discussed.

Canon XSi (cropped sensor)
Sigma 8mm 3.5 circular

I will be taking a variety or panos to include interior and exterior. I've seen that the R1 is great for outdoors but maybe not so great for indoor shots unless it is a flat ceiling, but easier to use than the NN3?. NN3 sounds like it might be a good all around mount but maybe a weight issue for my equipment? Ease of nidar shots? My head hurts now...

Any recommendations on tripods? Mine currently has lower supports and would create a large foot print.

Thanks in advance for all your help!
