Hi John,
both Robby and I have been down the OAG road, and while some can use them we have both opted for the separate guidescope (as has our learned companion Mr Ponders it seems). More weigh, some more cost, but given a few things being right, eminently easier to use (in my opinion).
My question about one or two OTA's was more that I thought you were looking a longer focus OTA for planetary webcamming, and a shorter focal length OTA for deep sky and wider field imaging. I reckon you can do both with some scopes, for example the MakNewton (f6).
I have definite views on forks, and much prefer the GEM for all imaging. If visual is your only requirement then a dob base is where you need to be.
