I am using a Roland E-56 that is owned by my church. I can't find any information on how much it is worth. They may be interested in selling it to me but I am not sure of its value. Does anyone know a site that might provide this type of information? Thanks KJ

Are you sure it's a Roland E-56? An E-36 goes for around $400, an E-66 around $600-700, an E-86 around $800 and an E-96 around $1000. Hope this helps.
