I'm new here. Just noticed there didn't seem to be any messages about the 1660. I've had one several weeks and have been very happy with it. It includes a 35mm film adapter that can hold a strip of up to 6 negatives or 4 mounted slides. I've scanned many slides, some negatives and some prints. Fortunately most of my slides and negatives are very clean; I get great results with them. I've needed to do only minimal post processing. I have a collection with several samples on my fotopic site if anyone is interested. This scanner runs about $120. Good enough for me!
