Hi Richard
..... I have a 10" collapsible Dob and before that I had a solid tube 10" dob. The reason I bought the new one was mainly because I loved the look of it, and love the way it folds down easily to put in the car.
As others have said - solid is a bit cheaper, collimation - I have found, is not a huge amount of difference. The collapsible is a bit heavier, but easier to manage, except if a 12".
Dont forget to look on the classifieds here - there is a 10" saxon (pretty much hte same as Skywatcher).
Good places to buy from are Bintel, Andrews and Astroshop.
Let us know what you get.
