If you can, get a Linocolor. A little more expensive, but better quality guts. Also check to find out what the DMax is of whatever scanner you are looking at. The more Density Maximum, the better ability to see into the shadow area. That way you do not end up with flat shadow's. AGFA's are pretty good too, although not that exacting for color work. If you need to be dead on for color work don't be afraid to spend a few extra buck's, it'll be worth it in the long run.
