I bought one for my nefews about a year ago(with my sisters money offcourse). payed 600 euro's which is still a fair price if its in a good condition
Overhere in Holland they sell for 500 to 700 euro online private, and a little under 1000 euro from a dealer..
Its still a great startup keyboard for youngsters that want to learn keyboards because of the super quallity keybed... and the still very acceptable sound quallity...
