Tracy,
Custom created PPT slides are better in my opinion. As instructors, we don't always follow the exact order of chapters, or topics within a chapter anyway. I prefer to take time to cover material as I think it should be. I can always use slides from the image library if necessary. And since you stated you don't have access to a rejector, then I suspect you may access to the OH projector -- I miss it, and will still use it from time time to time.
