miden you definately need to keep trying to sell it until you get what it is worth. While Ketron may not be so well known in Australia eventually you will find someone who knows what it is worth. The SD1+ is an excellent arranger keyboard. The reason a dealer wouldn't want to accept a trade on a Midjay is that they never want to trade in an item that is worth more than the one you are buying.

While you may not be able to sell it as quickly as you'd like persist until you find the right buyer.
