Another question is how big does a dobsonian have to be to start using a step or ladder to view because I cant see myself using a step, I just want mount and tube and DSO hunting. Cheers guys thanks.

1, You don't need another scope, you need to use the 8" you already have. What do you expect the 6" achro or 90mm will give you over the 8"? - nothing is the answer. How many DSO's have you seen with the 8"? - if you have knocked down most of the Messier objects and all the NGCs that are plotted in a sky atlas like Norton's or some of the other condensed atlases, then perhaps you are ready for a larger scope.
2. In the case of a 14" it would have to be F4 or faster, and you would need to be tall to do without any ladder or step at all. My dob is 80" focal length and all I need is a two step stool to see the zenith.
