With very rare exception, I never enter 'em. If the prize is of substantial value people will enter 24/7 several hundred or more times a day. I'm reminded of the recent Suzy Orman unlimited entry sweep. The site crashed due to the volume of entries. Once in, people wouldn't log out, so the site crashed. I believe the prize was $20,000, so the sweeping enthusiasm was understandable. Greedy @#$$#@#$ that we are.
