If you want 6" and an EQ mount: how about the "Skywatcher Black Diamond 150 x 750P complete with EQ3 equatorial mount and dual axis motor drives with hand controller" at Andrews for $749 (see
http://www.andrewscom.com.au/site-section-10.htm - go to Skywatcher and scroll down)
I agree that EQ mounts are a pain for eyepiece position at times, but you can always rotate the tube in its cradle to get the optimum position...

PS: If you aren't fussed about an EQ mount, I see there is an 8" collapsible dob in the classies at the moment for under 1/2 of your budget.
