Gary,
Good luck with your purchase.
I am keen to hear about your CPC 1100 as I too am thinking at the moment that it is time to sell the 10" Dob and upgrade into an 8SE with GPS. The Dob is great but too bulky to easily transport.
As far as your EPs and other accessories go I am sure one of our more experienced IISer's will come along and share their thoughts and experiences, and I'll be here looking over your shoulder
.
Clear skies and again all the best with the 1100.
