Unless you get a good telescope and learn how to use it, you will experience nothing but frustration. At 100x, things move out of the field of view so fast that the telescope is hardly usable without a motorized tracking mount. For home astronomy, 100x is enough, but you can see a lot at 30x, including the rings of Saturn, the moons of Jupiter, the Orion nebula, craters on the Moon, and much more. Aiming the telescope is an important consideration. Good telescopes have sturdy tripods and mechanisms that allow the telescope to be slowly and smoothly panned across the sky and to stay in place once they are aimed.
Cheap telescopes are almost impossible to aim and keep aimed.
Larger lenses or mirrors are much more important than large magnification. Telescopes below about two inches in diameter are not very useful. Three inches and up is much better. The astronomy magazines carry numerous advertisements for good telescopes. You might find a used one for much less.
