I would recommend a reflector on a dobsonian mount. They are easy to use for beginners and easy to assemble. I have a 6 inch dob reflector and I can fit it into my car with ease. Dobs are great planetary scopes, especially if you can afford some good eye pieces aswell. I can get a good view of Saturn and Jupiter with my 6 inch. It also depends on what you want to look at in the night sky. I love looking at planets but other people love looking at galaxies, globular clusters and comets. My particular scope is ok for big galaxies like Andromeda but smaller galaxies require a bigger scope. Dobs are reasonably cheap too, which is why I bought one. I'm now considering buying a refractor or a Schmidt- Cassegrain, which are more expensive but I think Im ready to move onto a scope with more power.
