I've sat in audiences and listened to people critique other players and make fun of them and how cheezy their keyboard or vocals sound.

To me this is the priority for me; not to sound cheezy. Most of today's keyboards have great sounds that don't sound cheezy with some exceptions.

I really think it boils down to the styles and whether they fit the songs your playing and if they make people want to dance.

And I must say, I just bought a 61key arranger instead of a 76key on PRICE differential alone.
