All,
Thanks for your advice. I tried the Yamaha DGX-640 and Casio PX-350 over the weekend and went with the Casio. The thing that sold me was the sound of the piano tones. I also really liked the compact and light-weight cabinet. Admittedly, the Yamaha had better accompaniment sounds and features, cost less and came packaged with a keyboard stand. It was a tough choice but they were both excellent products.
I'll be posting some more new songs in a few weeks in the User Showcase. Thanks again.
