I actually just ran across the PlusTek OpticFilm 7200 7200dpi slide scanner, which Amazon sells for less than $200 (about $90 more for the one with IR scratch detection) and which seems to be getting good reviews, especially considering its price, even from photography web sites. I've got a few offers to potentially borrow a scanner, but $200/$300 to scan in all those slides seems like not a bad deal, especially considering that I'll have no use for it once I'm done and can eBay it.
