Super 8 movie camera extras

I've been doing extensive research these past couple of days about the super 8 cameras, the film needed, how to transfer it to dvd and watch it. It's been pretty easy to find answers when I know where to start. I was able to contact a professional and he told me not to spend a lot of money on the cameras to begin with. He also told me to get the canon 814 vs canon 514. I am interested in getting the xl-s. The xl-s is a bigger version of the cameras but still handheld, there are bigger versions of the xl's too. There are also two version to most of the cameras; with sound and without sound. I am looking for the camera that I can shoot with and without sound. I've basically found everything I need for these cameras. I will wait a bit, maybe a week or two before I purchase a camera. I was going to purchase one tonight until I was told that the price should be lower. I've heard of people purchasing the cameras for $20. I would love if I could luck out and do that. With ebay, you never know. I will keep my ear to the grindstone.
