Depending on how 'deep' you use your Arranger keyboard, I believe most of the new high end 'keyboards' that have been released in today's market initially have some 'bugs' or things that can be improved upon. For some manufacturers, it was hardware related with LEDs not lighting up or low quality output audio jacks or flickering screens or .... Now it is true that some companies are capable of acting/reacting faster to respond to and fix these issues, but the most important thing at the end of the day is support for the instrument and being able to deliver a product that customers need and are happy with.

Now after the manufacturers have "delivered", which of their products best satisfies your needs and offers you reliable product support especially after sales? Answer that and you'll know what instrument(s) to get.

Thanks,
