I have an Epson Perfection 3170 which ran happily with our previous iMac but since we bought a new iMac last month and loaded Lion I now get 'You can't open the application EPSON Scan because PowerPC applications are no longer supported.' I was very happy with the 3170 especially its ability to scan A4 reflective or negs / slides transparencies with the various mounts. I am quite happy to eBay my 3170 but have no idea what to get to replace it. Any recommendations would be very welcome. I scan many 35mm negs as well as A4 documents so want a flatbed scanner which converts to a film scanner like the 3170.
