My wife has a Dimage x and it is great. We can print 8x10s, with a great deal of cropping, and it is difficult to tell them from a film print when a negative has been scanned and a digital print made. and that's using the normal mode then saving as a TIFF in the computer. If the highest mode is used, it is impossible. As a professional photographer I still hold to film for professional work, but the Dimage is great for any thing else.
There is a new X, Xi or X something, which is an improvement on the X - 3 mb instead of 2 mb. Costs a bit more and may not be worth the extra if you get a good price on an X. X is no longer available in the USA except for dealers trying to get rid of their stock which gives some very good prices.
