Something that you might want to keep in mind is shotting reversal film on super 8mm and buying a projector to view your footage. Don't spend money on transferring your footage to digital right away.
If you have a local photo lab in your town you should see if they transfer super 8mm to video, they are in the market to do this for people that want to transfer their old home movies so it's not as good of a transfer as you would get from a professional lab, but it's still pretty good.
The local place near me charges 12 cent per foot which works out to be $6.00 per super8 cart, not bad at all.
Oh, if you do go to a place that is in the business to transfer old home movies they more then likely won't be able to transfer negative film.
I would also suggest that you don't try and shot something to complex, story wise with your first roll or two. Just go out and shot things you'll find interesting or experiment, epically if you get a camera that does time lapse, and different frame rates. Shot every frame rate you can so you can see what all the different things your camera can do.
