You have been given some really good advice so far. After many years and even with the larger scope my 8" scope is the most often used one.
I agree with Erik, I cannot see any justification in the extra expense of a Skywatcher. If you get a new GS it will come with a crayford focuser and a few eyepieces that will get you going. Only extras needed are a red torch, plansiphere, cheshire collimator (essential), a stool (to stop dobber's back) and a desire to get out and have a look.
Don't get into the "upgrade" path too soon or you will end up with a lot of expensive paperweights. The eyepieces these scopes come with are plenty to get you going.
Keep looking up
