Even when you add a focuser, a rotator and dew control you would almost have enough change left over for an sbig stt3200 with self guided filter wheel and ao8t..If you want to hunt dim galaxies you would be hard pressed to go past the 3200me sensor. 6.8um pixels, 85% QE and huge maximum well depth.

At the fl you plan on imaging I would strongly recommend ao. Even at only 1000mm I find the difference is quite noticeable.
The EdgeHD 14 is very tempting, it is very difficult to find what the issues are with any scope because the net is filled with glowing reports from the vendor etc. is there anyone in this forum that is successfully (or unsuccessfully) using the edge HD 14 in a remote observatory with heavy gear sitting on the focuser?
