I think 28 Days Later had a great storyline, and it was certainly distributed pretty widely. I can't say whether or not it was Panavision lenses, but I felt it looked pretty average. To me, it looked like a student film with a half-decent budget, or a british television drama. That's obviously the look he wanted, but I personally wasn't a huge fan. Obviously didn't really hinder much of the movie's success though.
You won't be picking up one of them for <$500

I'm not sure why you're so averse to DSLR if all you're looking for is a good quality camera that can get the job done. DSLRs certainly have their issues, but they are most certainly good quality cameras that can get the job done, and in that price range is going to be your best option. It also doesn't leave you with outdated standard definition technology, an internal tape drive that is likely on it's last legs, all the time in post capturing in real time, and general technology that is 10 years old.
