Ok here we go, first off... man I'm jealous your going to Sasquatch. I wish I would have gotten tickets before it sold out. If you know anyone with an extra one please let me know.
So I went through the Super 8 process a few years back, I bought a camera, a few rolls of film, and had it processed and telecined to mini dv. The footage was amazing and it was really fun to shoot, just super expensive.
As far as camera's, I bought a NIZO because I had heard from multiple sources they are the best for the price. I got the NIZO 701 Professional and it was like $250 on ebay. Make sure the glass is clean, motor works well, and light meter is working properly. Most Super 8's have auto exposure with the light meter so if that is broken or malfunctioning all of your footage will be under or over exposed. There are super 8 cams on Ebay for like $15 but if your going to be spending hundreds of dollars on film don't skimp on the camera, buy a NIZO or at least a properly functioning cam.
As far as film, I used Kodachrome 64T, it WAS the best super 8 film and had great colors, but as of December 30, 2010 there are no more labs in the US that will develop it. So you are either gonna have to shoot Ektachrome 100D Super 8 50ft or a black and white alternative. The 50ft rolls are about $10 and run for 3 mins at 24fps, anything like 60fps will cut that time in half.
As far as developing and telecining, use http://www.dwaynesphoto.com/
down in Kansas. They are the best and are super helpful on the phone. The more rolls you develop at once the cheaper they get. I would recommend calling them on the phone and working out your order that way. It is $12 a roll of film to get it developed and around $8 per roll to have the film transferred to a quicktime file on a DVD. They are super friendly and do everything in house so it's really convenient.
So to wrap things up... It is about $10 a minute to shoot super 8 and the footage and the quality is hit or miss. It is really fun to shoot and I would do it while you can because people that develop super 8 are closing left and right. The retro film look is amazing and so is the whole process of waiting weeks to see what you get back. I shot 3 rolls and would love to do more in the future. I hope this helps.
0:55-1:35 was my first roll, from a few years back.
