scanning - Inexpensive method of digitizing large numbers of 35mm slides?

I have a huge collection (over 1000) of 35mm slides that I'm considering digitizing. So far the cheapest I've seen is ScanCafe, at $0.22/slide for large orders, that would be $220 for 1000 slides. I also considered getting a slide scanner, but I don't want to get one where I have to sit there and feed it 4 or 5 slides at a time, it would take years to get through them all. There are very few automated slide scanners that would take either a slide carousel or a stack of slides, and they all seem to be very expensive, with poor reviews (they get jammed, eat slides, etc)
