While it is true that most cataclysmic variables are quite faint in quiescence, there are some that can be observed throughout their cycle, and a great number of them that are bright enough in outburst to detect visually with a 6-8" telescope.

In hopes of encouraging new observers, and those who thought these stars were beyond the reach of their aperture, we have put together a list of CVs suitable for small telescopes. They are all brighter than 13th magnitude in outburst and are active enough that you won't have to wait long to make your first outburst detection.
