For Christmas last year, after a nice craft season, we got a Canon 9000F, and it seems to do a pretty good job. There is software to enhance things even more, but so far its built-in software seems to be adequate.

It will do 4 slides at a time, and though I have not done extensive tests, it will allow me to scan stuff I never thought I get to. It also says it has the ability to 'straighten' the curve of a book that won't flatten out totally....but I have not tested that yet.

I have a long list of projects for it, and I have my fingers crossed.
