Louie, are you planning to get the SXVF-AO unit and the remote guide head?
After having a look at some of the options available and some of the SX camera models, I think my next camera will be a tough decision... STL11K or SXVF-H35... For the price of the STL11K you could have the SXVF-H35 (same sensor) SXVF-AO and the guide head and half of a filter set...
