For my bigger rifles I have either Ziess Conquest or Leupold on them. The first time I looked through one I was amazed at the difference in low light. With a cheap scope you might have to pass a shot up because you can't see well enough to shoot. With my Zeiss Conquest we hunt at night for hogs and if there is any moonlight at all I don't even need a light. With a lot of the cheaper scopes I've looked at I would have to have a light to be able to shoot. If you can't afford a good scope right away you can always replace the cheaper one later.
