Anthony,
If you are just starting out with Super 8 equipment, I would definitely recommend something along the lines of the Canon 814 Auto Zoom like Tron X recommended.
I recently bought one on ebay, but I believe the exposure meter was dead (I went to B&H to try new batteries but they did not fix). With this camera, exposing is not really a big deal if you understand apertures. You just flip the exposure setting to manual, and set according to your light. The results I obtained over a weekend trip were great with the Ektachrome 100D. 64T is being discontinued per Kodak so I would only be concerned with the 100D compatibility for reversal, or maybe 50 if you like Velvia. This Canon 814 Auto Zoom will autiomatically set the 100 film speed. Another great thing about this camera is you can engage/disengage the internal color conversion filter.
When I shopped around, I just read online sources and found cameras that could read a wide range of films. You never know when something else may be released.
