Biggest sellers in my area are digital pianos like CP-300, and RD700...a lot of traditional stuff like Celtic and Acadian fiddle music, plenty of jazz players and classical performers means there is a big interest in piano based instruments...88 keys are, by far, the most requested.

76 note instruments, especially those with unweighted keys, aren't taken seriously.

I'm sure it's different for other cultures and countries, but that's how it is in my neck of the woods.
