This is often the one which gets used the most because it is so easy to run out in the yard with. If you have small children you might be relieved to know that there are some very nice, small telescopes these days that are NOT mounted on a tripod and involve NO knobs, lock-nuts, wires, alignments, or undue mental anguish. Astrophotography has taken great leaps in recent years, with digital cameras and video recorders. For traditional film photography, plan on putting out some bucks. A less expensive outfit that does photography will sacrifice good optics for bells and whistles.
Low magnification makes solar system views less interesting.
Refractor - uses lenses to bend the light. This is what most new-comers to astronomy imagine. Lightweight and portable. Good for solar system observing at medium powers. Since the light you see must pass through the optics, good quality is especially important and expensive.
