Because best quality and cheapest price are typically traits that go together?
Be realistic. If you want cheapest price then you DON'T want best quality. You'll want to prioritize your needs to make a reasonable selection.
If there is a particular type of use you have planned than it's critical that the camera can handle that particular use -- regardless of price. If this is a general purpose camera and you don't have a specific use then you can prioritize on price... but keep in mind that there will simply be things that the camera can't do.
You wont be buying a $99 camera and then using it to shoot sports games indoors, under poor lighting, from the top row of the bleachers at the very back with the camera at maximum zoom. That's not going to happen.
