I might have one coming up for sale anyone know how old they are what they might be worth? Were they top of the line or mid range?

Hey Mike, I used one for a couple years..the higher the E series number, the better the model..It is a light feel 61 key model that has song play back from floppy..It has many parameters you can change in live play..Works pretty smooth..The styles are similar to the E70 and RA90..
I replaced it with the module version..RA95..

Street value around $150-$200..Original dealer cost was around $660.

28 voice polyphony, but very good allocation[Sound Canvas priority system]..

I used it from 1993-1995..with my trusted JV1000, at the time..

Thanks Fran I got a call from a girl wanting me to sell her late fathers musical instruments.

I own a Roland E-60 which I am happy with its 76 keys and some of its styles still to this day. Good on board audio speakers too.
