Hi Tyler,
Don't get discouraged with shorts - after the movie, I showed a bunch of shorts, old cartoons, black and white songs, etc - and to my suprise, the audience was still captivated! They didn't move from their seats until I turned off the projectors and started packing everything up.
Since you're so new to this hobby, if you want, pm me your address and what genre you might like and I'll dig through some stuff I'm currently getting rid of for basically nothing on Ebay and send you something gratis (specify if you want 8mm, super 8, or 16mm, or a combo).
Hey - now that I think about it, if you don't mind vinegar, I could send you some pretty cool stuff (Elvis, etc) - just be sure to store it at least 20 feet from your regular collection!
