Thanks for posting this. The idea of making 35mm is a lot of fun to think about. It certainly rounds out the emulsion-making picture. I suspect you got a really good deal on your splicer. The ones listed right now are considerably more expensive. But, never say never! I'll be checking ebay regularly. I think you found the hot Xmas toy of 2010
A reminder note: If anyone is really interested in making roll film, and can forgo 35mm during the learning curve, 120 isn't perforated and is straightforward to produce, load on reels and in the camera, shoot and process.
