Pros: Speed, scan quality
Cons: Price

I didn't know anything about scanners but I needed one as I love shooting with film, but I like post-processing my pictures.
So I followed the recommendations of the main reviews and forums I could see and went for this Coolscan. Minolta's scan dual IV was cheaper and maybe very good too, but everyone says Nikons are better...
So this scanner is really impressive. It is fast (less than 3 minutes with ALL enhancements activated), and the result are always excellent.
It is also very easy to install and operate, so I really have no complaint about this scanner.
Finally, it looks small on the pictures but it is very deep so be careful if you don't have so much space.
