Hi,
I think you said you wanted to put your 10 inch dob on a mount. If you go the HEQ5 route then while it may work for visual I dont think it will work for photos. The EQ6 Pro may be the better bet here i think.
I may be wrong but, for visual your 10 inch DOB will blow away the ED80, 100 in terms of light gathering and image brightness. The ED100 will give far prettier visuals in terms of crispness of image, jewel like stars and so on but at the end of the day it is only 4 inches and so cant compare with the 10 inch as the 10 inch gets 625% more light.
So why get the ed100 rather than the ed80, the mount is important but also you have to decide what image scale you want. The ED80 has a shortish F length so widefield will be great (with a field flattener) but small objects will be tiny if you go the DSLR route.
Anyway i think
(1) go an EQ6 for stability
(2) get a second hand DSLR 350D for imaging
(3) without guiding and a coma corrector you will soon be unhappy
with your photos as you will see lots of trailing and seagulls so buy a coma corrector a small 80mm 80 buck refractor (100 bucks) of ebay for guiding with PHD, a second hand DSI for guiding camera.
(4) use all the above with your 10 inch DOB and once you have decided what image scale you wish to image at then buy a refractor or mak or whatever that fits in with that. At this stage you may decide that you are happy imaging through a 10 inch dob and opt to spend the money on a proper cooled SBIG camera.
Anyway just my thoughts
