Funny you should ask. I just got one. After reading numerous reviews I got one of the 'Ion' brand converters. It had a better customer satisfaction rating but I think it is one of those things where you get what you pay for. It does the job but it doesn't capture the whole 35 mm negative and there is some minor cropping. I don't think the color or brightness is perfect either but these are things that can be somewhat corrected with a photo editing program. I'm sure the more expensive ones are better but you approach a point of diminishing returns. Having it done professionally is an option but you need to figure how many you have. I have seen shops charge in the 70 cents a piece neighborhood and that can mount up if you have several hundred.
