Depending on the power and variable range will dictate cost. But you get what you pay for in cheap scopes. I've bought used firearms with the cheaper scopes and everyone has been removed for sale or dumped in the trash because of the poor quality. If your young then you won't notice the fuzzy focus, blurry images, non linear adjustments, etc. Older eyes tend to notice these things faster because they wear one down during a long day of varmit hunting. Been there done that years ago with no desire to every return and wishing I had saved my money for better optics.
