This type of telescope has a long, slender tube with a lens at the front that “refracts” the light from the sky. This is the oldest style of telescope and has many advantages. They are simple to use and understand, need less maintenance, and typically give very sharp views. Unfortunately, it’s difficult and expensive to manufacture large diameter versions of these scopes, so they are fairly small in aperture.

Buy risk-free: When it’s time to trade up you’ll get the most value for your used gear.
