Let me explain the way it works here in the USA.
Bell Duovox Corporation is the United States Distributor. They buy product directly from Ketron in Italy. It is Bell Duovox's responsibility to establish a dealer network which buys from Bell Duovox Corporation and then sells keyboards to you the customer. I, for example, own a music store in California and I buy and sell products from Bell Duovox, Generalmusic (distributor is in Chicago), Yamaha (Yamaha Corp. of America), Roland (Roland Corp. US), etc. All of these Distributors buy from their parent companies in Japan, Italy, etc. Not all products made are distributed in our country because the distributors or the Manufacturer doesn't think a certain product might be good for the USA market place. We don't always agree, but that's the way it works! The warranty is supplied by Bell Duovox Corporation as a distributor of Ketron Products. No one but a Distributor may buy product from Ketron in Italy. Not a music store, not a musician, only a Distributor.
If you are saying that the distributor is not offering any warranty, I would suspect that this is not a factory authorized (Ketron) distributor. If they were, they would be offering a warranty. If, on the other hand, they are buying product from another dealer in another country, then there would be no way to offer a factory warranty. Warranties are always honored in the Country they were sold to originally and not if they are transfered or sold to someone in another country. When I was in Italy a few weeks ago, I had to purchase a new camera. I made sure that the warranty inside the box was written as an "international" warranty. This is one that is honored no matter where you live or take it to be fixed. This is common on cameras but unfortunately, not keyboards. We are quite fortunate here in the US, to have such good distribution and factory warranty service provided by Bell Duovox. In the event that I need service fast or parts fast, Bell Duovox has always been there for me in a prompt and professional manner. Many customers wish there were more dealers or better educated dealers in the USA, but this is for Bell Duovox to decide how they want to structure their dealer network. Sometimes, especially with smaller products, the manufacturer might decide to switch to a different distributor because they are not doing the job expected by the manufacturer.
I'm sorry about you problems buying Ketron products in Australia. Hopefully, if you contact Ketron at www.ketron.it
and email one of the contact people there, they will be able to answer your questions and concerns.
