1. The mirrors and other components in reflecting telescopes are considerably less expensive. Mirrors can be fine tuned for optics much more easily than lenses can be ground, resulting in less expensive telescopes. If cost is your primary concern, you'll probably want to get a reflecting model.
2. However, they aren't always the best for beginners, as reflecting telescopes will require a little more maintenance as compared to refracting telescopes. Mirrors require regular recoating, as often as once every few years. They also must be handled very carefully as compared to refracting telescopes. Finally, a reflecting telescope requires more collimation, or adjusting, of the optical components.
3. Reflecting telescopes do usually create a more faithful reproduction of the sky than refracting telescopes. Generally you won't have as many problems with "aberration," or the faint colors that surround some celestial bodies like Jupiter and the moon.
4. For anyone brand new to the practice of astronomy, convention says that the refractor is more practical choice. If you know for certain that you'll be using your telescope and regularly practicing astronomy, though, you'll probably want to get a reflecting telescope right off the bat. Reflecting telescopes are better for viewing very faint objects in deep space and are considered preferable for astrophotography.
5. You'll find great selections of reflecting telescopes and all relevant variations of them from brands such as Celestron, Meade, Zhumell, and Bushnell. These brands are considered to be the best in consumer optical products ranging from binoculars to telescopes.
