hi dave and astrobot
i own a 12" SW flexi-tube goto. I am quite happy with it.
as for moving it around, there is one bolt to seperate the tube from the mount. easy. i drive a BA falcon, and put the tube in the boot and actually have to put the mount on the front passenger seat. the rear doors on the BA falcon don't open wide enough (i think the BF onwards have more rear door range). I don't think I could transport the 14" with my car!
When moving around i don't dismantle the mount either, i am able to move around easy enough with the mount off, but if you've got a bad back etc / traversing uneven ground / or have to cover more than 50m it may be a struggle.
i enjoy the ease of setup and the clutch setup really is a good feature. setup / imaging etc it really is the LazyAstronomer's perfect scope. i'm still to suss out exactly where the tracking weaknesses are eg zenith or downlow, i think as far as ds imaging goes i think it was struggling well perhaps rotating a bit more directly up than closer to the horizon..
good luck
Rusty
