Thanks, Ted, for your very concise but spot-on summary of the differences between the two series! I think I'll take a chance on the ctk6200. One more question: on both the 6XXX and 7XXX models, preset chord progressions repeat up to a certain number of measures, depending on the preset selected. In the 7XXX series, are user-created progressions also limited in the number of repeats, or are they basically an endless loop? Thanks again.
