Dirk,
Welcome to IIS
My advice would be to find your local astro society and go to an observing session and have a look through as many scopes as you can BEFORE parting with any money.
In the meantime, get yourself a planisphere, red torch and a simple pair of binoculars and start learning your way around the night sky. It doesn't matter if you get a go-to later you really need to know the basics of navigating the night sky.
Take your time and you will not be disappointed.
P.S. I would recommend an 8" dob not a 10"
