Hi Ray, I have had a solid tube 12" Saxon dob for about 5 years now and have had no problems with it. I find its excellent for finding those deep sky objects and it holds collimation well.
In my opinion, if storage and transportabilty is not part of the equation, then I would go for the solid tube dob and the money saved could be put towards a couple of nice eyepieces or a good laser collimator.
I also think Daniel is correct. Saxon, Skywatcher, Orion, etc - the mirrors are all pretty much the same.
Pete
