Skratch,
There are alternatives to conventional approaches to shooting, processing and posting your films that can keep your costs a bit more manageable.
As an example:
I have a CP16R/A with 3 mags, 3 batteries, a power supply and a Canon Cine II lens that I picked up from the local film school for $375. I suspect that many schools have periodic closet cleanings, so deals are out there.
I also used to have the Super 8 version of a Workprinter, which is a desktop telecine that works with a Macintosh or PC, which you would probably use to edit, anyway, since you mentioned telecine. The 16mm version is about $2000.
As Matt mentioned, you can get short ends and recans of 16mm probably cheaper per minute than you can super8 from Kodak. You also have a far greater pallette when you work with 16mm. My understanding is that processing is on par, but I haven't sat down to work it out for myself. Might not be fully accurate.
As you get out of the financial side, you begin to get into personal preference and convenience. Longer run times per magazine load, lens options, repair options, projection options.
I know of a cheap Kem 16mm 4 plate editing bay, in case you're interested. I think it comes with splicers. I know it has a picture head and improved sound head that uses a stereo amplifier.
A little creativity, patience and perserverance will land you a killer kit for very little more than you're spending on super8.
And just to show I'm not prejudiced, I have a Sankyo Supertronic and a Canon XL310 for low light photography, both with anamorphic lenses, that I use as well. Just depends on the project.
