GSO Dob tension spring system, good enough?
I am trying to choose a 10 inch dob and can't decide which is more inportant. I love the fact that the GSO dobs have a dual crayford and I love the fact that the skywatchers don't have the spring tension system on altitude. Which will bother me more if I buy. Does every GSO dob need some kind of counterweight system, or is the spring system adequate. Not to mention the GSO is sginificantly cheaper and has more free accessories(laser collimator, 2xbarlow,cooling fan, 26mm 2"SP and 1.25 10mmpl Skywatcher only come with two 1.25 PLs)). But if the scope doesn't hold altitude how frustrated will I be. I don't really want to have to fool around with mods or counterweights. SHould I spend the extra money for the skywatcher? Or will I be happy enough with all the extra accessories and the spring system on the GSO?
Cheers
Jason
PS. on all the pics I've seen at various sites the 8" and 10" skywatcher flex dobs have different focusers with the 8" looking the lesse quality of the two. Can anyone confirm this, does the 8" skywatcher has a lower quality focuser than the 10"? On the skywatcher USA saite they are the same, but I live in Korea and can only get the Non-usa version.
