Hanora,

You are looking in the right direction with the 6" Dob. An 8" brand new will likely exceed your budget, and often the optical quality can be better in the 6" than the 8" Not sure of the focal ratio of the one in the link, it looks about F6. Check other suppliers, an F8 (slightly longer) will give better views of the planets.
