I don't recall having any problems. I've had a question or two and I can pick up the phone and call Ted Kraus in New Jersey, the Sales Manager for Ketron in the U.S. He either answers the phone or calls me right back.
He can arrange for you to buy one. You can ask him about a trial and he will arrange it.
The number is on the new Ketron website. www.ketron.com
There is even a demo song by ME on there.
