Well Daemon, if you talk to our mate Robby here, he'll sing the praises of the Celestron 9.25. I considered buying it but it was beyond my budget for combined equipment. Apparently its one of the best for the cost.
Yes a good quality dedicated astro CCD will give better performance than a Digital SLR, and yes the B&W using filters would be the prefered way to go. Everything else is basically a cost compromise. If you can afford the double chip ccd then from what I understand its the preferred way to go. Helps deal with the issue of mirror shift with scts. However if you aren't interested in a widefield refractor to piggyback for imaging as well as guiding then you can go for any old refractor as long as it takes a 1.25" eyepiece so you can mount a ToUcam for guiding. If you get an LPI for guiding then you can even get the elcheapoest refractor with a .925 eyepiece sleeve as it will fit after removing the 1.25 adapter.
I'm sure Eddie T or some of the others that have CCDs will pipe up here, but from what I remember the SBIGs etc are somewhere round the 11mp range whereas the DSLRs range from about 6 - 8.2mp??
Hope this helps
If you like the Losmandy but not the goto (neither do I for the price) then maybe consider an argo narvis.
