Quick thoughts...
A C11 and a C14 are in different leagues... A 14 is a long focal length unless you're really into planets IMHO. I have a 2500mm scope and seeing is always the limiting factor, even with a 9 micron CCD. The best scope is the one you use - I would never have a 14 inch scope unless it was on a pier permanently.
With mounts you get what you pay for along two axis. Capacity + Accuracy. If you want both capacity and tracking/guiding accuracy it's a multiplier on cost. Yet to see in person but if I were buying a do everything portable, spend the kids inheritance portable mount I think these are had to go past -

If you go for an MYT (a good choice) then I have the very expensive and very excellent paramount pyramid tripod to suit sitting in my shed basically brand new which I would sell for about 2/3 of new.
