Larger sized refractors include telescopes with apertures above 80mm to 200mm and even higher. In this class, you can start comparing the pros and cons of a refractor telescope versus a reflector or catadioptric with a similar aperture size. You can purchase one of the other types of telescopes with a comparable performance and a smaller cost. For the larger sized refractors with a 200mm aperture, you can pay upwards of $10,000 for some models. Astronomy enthusiasts with a die-hard allegiance to the refractor telescope cite the low maintenance, ease of use, and bright, clear contrasting images as a reason to stick this type of telescope, even with the high price tags.
