1. Usually not, although the newest skywatcher Dobs coming out have a tracking dob mount. see the thread called 14" Dob or something in the forum. even with the very newest dobs that can, frame rotation would be an issue for imaging, unless (and i am happy to be corrected here) the base was mounted an a plinth that was of equal angle to your lattitude and pointed to the SGP? although for visual use it would be fine, the dobsonian mount is the instruments greatest strength, and greatest weakness ...
Although to answer your questions properly, yes it can be done, usually with an Argo Navis and a CAT etc. still costs loads !!
2.Orion (USA) and Skywatcher, although again, just announced, and not alot of news yet.
3. ? Cars when crossing the road?
4. Loads. the only current price i have for the 12" is $3100, whereas the ordinary model without tracking can be had for $1150. I called Andrews, and they said they hadnt posted anything online yet, as they would do so when they had thier very best price. for an Argo Navis and CAT? well, the AN is very reasonably priced, and a great piece of kit .. the CAT will cost a little bit more
