Rob I started with an 200mm f/5 reflector (a skywatcher) but not on a goto (which is still my one and only
)...have had a few frustrations working it all out but am still pleased with my choice. The goto with autoguiding port is a great idea to facilitate imaging at a later date if thats where you want to go(to).
Don't forget also that this forum is an excellent source of information both on past threads and by asking questions.
Enjoy making you choice, you learn a lot just by researching. And it SO exciting when you finally get the scope.
