I bought the Roland E 80 when it came out to supersede the G 70. It is a great keyboard but i only use it in the studio as at 55 pounds I can't carry it out anymore. Roland never did really support it either.
I have a 25 pound Technics KN2600 the last one they built after the KN7000 that I take out of the studio. It walks all over the E80 and the tyros I have.
