GSO mirrors are surprisingly good, and I recently used one in a 10" imaging newt I built. The scopes are fairly heavy but a 12" can be easily moved around with a trolley. The solid tube 12" can fit in a car to travel to a dark site but it's a bit awkward to handle. If portability is important the sectional dobs might be better for you.

+1 - I have now used 4 GSO mirrors (6, 8, 10 and 12 inch) and all good optically. As with any optics, there is always the chance that you will get one that is below par, but I think that the odds are much more on your side than some seem to think. Mechanically the scopes leave a bit to be desired, but you can easily tidy that up a bit. The 12 inch Dob really needs a grab handle of some sort - it is awkward.
