Hi Telmo
I own a E50 (61 keys) married with a Psr 3000since december 2005.
E50 is a "honest" kbd and you will have fun with one.
You will spent some days making your personal adjustments for styles , voices and effects.
I have an 1 giga compact flash card to store my registrations,styles and songs.
At the end will you have a dependable machine.
