I bought my Gammil from a CA company in 2004. They required classes to taken at their store as to keep their reputation from being damaged. If you weren't willing to take the classes they wouldn't sell you a machine.
They had many machines sold to out of staters. None of us had to pay California taxes. Of course we paid for delivery but it was reasonable.
In the 11years I have had my machine I have never needed them to "service" my machine. Once a rubber washer broke and my dh went to the local Ace and got a replacement......as per instruction by the tech dept.
Investigate them and their reputation on line for the machine you are looking at. ....jmho.
