The 910 does not have the screen problem that the 900 does. The 910 can play both the older SFF1 styles and newer SFF2 styles. The 910 Music Finder can call up styles stored on a USB drive, a very useful feature for anyone who uses the Music Finder. I am very happy with my 910. The downside is that any units you might find for sale are already about 10 years old.
