Have you used the IntelliScanner before?

I have nothing helpful to contribute except to say that's a pretty expensive machine that does what a smartphone app can do for free or cheap. However, if your collection is exceptionally large, I can completely understand wanting to have a dedicated tool to corral it.

ETA: There are a few apps in the Android market (I looked there because I have one). The nicest one seems to use Google Books for cataloging purposes.
