Super 8 Quest

On my quest to collect and own super 8 cameras, I'm facing a dilemma. Should I collect or buy a quality camera that I can also use effortlessly? I found two great cameras on ebay that I was planning on buying because they are cheap and in great condition. At the same time I found one great camera that might be better to have that comes with equipment and I might be better off having even though it cost more than both of the other cameras combine and then some. What should I do? Buy the two cameras that are in great condition or the one camera that might be better for serious filmmaking? I do what to collect, but I also what to use the cameras. Here are a picture of the cameras. Should I get the Bentley and Kodak together or just the Canon. If anyone reads this please give advice. I'm leaning towards the Canon.
