ScanWizard is very easy to show off, it is excellent. Software varies considerably among scanner brands. Frankly, in scanning, like in photography, I believe that user skill and attention will make a greater difference than the equipment. The original photo quality is also quite important. But the tools do count too of course.
Price is less a factor today.
Prices have drastically fallen. Hard to keep up with the current models, they change so fast, and prices are falling so fast. Scanners rapidly adopted 30 bits, and most of them are 36 bits now. If you have a photo quality color printer, and use 35 mm film, you'll really want a film scanner, for slides and negatives. The difference is because you are scanning the original film instead of a second generation print copy.
