Bill, I'd say forget the PSR2000 retrofit idea. Too clumsy & limited (can't even see the name of the files loaded). Save your $ and upgrade to the PSR3000 or Tyros instead. They both support MORE external storage than you'll even need.

The BIG advantage (to me) of the Tyros over the PSR3000 is onboard USER memory, which is significantly MORE than the 3000 has, allowing you to access a LOT more USER styles from the Music Finder than the PSR3000 can. Because I'm a big advocate of using the MusicFinder when I perform, remains an IMPORTANT advantage of the Tyros.
