Reflectors are popular due to their superiority to large, lens based refractors. They also do not distort colors as refractors do- a phenomenon known as chromatic aberration.
Because you get the most aperature for you money. The Dobsonian version of the reflector telescope is also very easy to setup and use.
They are popular because they are cheaper than high quality lens telescopes. They are available for $30 or a little more for basic designs.
They are fairly inexpensive but still offer amazing sights. You pay a lot less than a refracting telescope but you can still see the planets.
Reflectors are popular among professional astronomers because they are cheaper and have no chromatic aberration. Amateurs often use refractors, or Maksutov-Cassegrain telescopes which have both mirrors and lenses.
The biggest reason is price. They are much cheaper than other types. They also offer wider range of vision. They are perfect to build as a science project.
