Does the media you record on affect quality? For example 8mm, 8mm HD, Hard drive, mini disk, etc. I am looking for the best quality video in the consumer price range (less than $1000). Should I only focus on which camera has the best lens or should the recording format also be a decision maker. I'd like the convenience of a hard drive style but not at the expense of video quality. Or will I not be able to tell the difference between most of the cameras in my price range?
