I am with Geoff regarding fine focuser against rack and pinion. Plus GSO has right angle focuser.
I had 8" Skywatcher Dob as my first scope, very good scope and very easy to use.
If you want 8" I would go with solid tube since its not going to be big and its easy to put it in the car.
Also, i never had to collimate my 8", once collimated it stays like that even after long and rough trips.
With collapsible that might not be the case.
cheers
