I am fully satisfied with the 8100 "My second Plustek" I owned the 7500, not compatible with Mac, which I was very happy, But this is the reason for the change. The 8100 is even simpler to use, and gives the same excellent results. I think that's one of the best scanner on the market. I highly recommend it to who want to scan their slides and negatives. ease, having tamed the documentation. Reasonable price, given the results obtained.
