Hi Maverick,
I have an Orion 130mm on an equatorial mount and have just made my own Dob mount for the tube.
IMHO the equatorial is LESS portable than the dobsonian. With the dob there are only two main pieces to move, the base and the tube, and if its a 6 or 8" this is easy to do.
My experience of the Equatorial mount is that it is hard to pick up holus bolus and walk with it, which meant that I had to dismantle it to move it about easily. Also a manual equatorial is VERY HARD to get used to, especially in the dark. I think they are only worth it with a goto.
My money would be on the 8" Dob, absolutely!
Just my 2 cents worth.
P.S. I love my new Dob mount.
(Thanks alexander (mental4astro), pics will come as soon as I get hold of a camera (mines broken).
