Ok I think that you are set for panoramic cameras :-)
The feed-back on the latest Shen-Hao seems to be very good so you probably have nothing to worry about. I know that my Chamonix 45N-2 is very well made.
We were around Banff, Lake Louise and Yoho a couple of summers ago and just loved it so much. The Iceline Trail in Yoho is one of my favourite...
BTW in Banff there was a gallery with some nice pano that could have been with one of the 617. I do not remember the name of the photographer and the student in attendance had no idea of what I was talking about.
Let me know how it goes. I am still thinking about a SHen-Hao PTB617 which look like the same concept than my Chamonix (that is how I rationalize my lust).
