You get the finder, rings, case etc with the ProED and its now better glass than before.
Not sure about the F9 focal ratio though if this makes it too narrow for AP?
But then again, the 200mm newt is an F5 so maybe use that instead for fairly wide field shots?

200mm F/5 scope has a Narrower field of view than a 100 F/9. The 200 F/5 is faster, but narrower.. (100 F/9 = 900mm focal length, 200 F/5 = 1000mm focal length)
That said, A good point, a relatively cheap newtonian reflector + a decent quality APO is a great trade off.. you get a moderate narrow field from a 8" F/5 or F/6 newt, and a wide field from a ED80, and use them for alternating tasks of guiding and imaging depending on the target.
