I may be out of bounds with this question but I was wondering if this community has found an avionics supplier that has given pretty deals when the time came to buy these somewhat pricey units. In my research I have seen prices move 10% between suppliers but once in a while find a really good price break on one radio only to find out shipping was twice as much or the other radios were much higher. If anyone has had particular good service, price breaks, customer support I'd appreciate the info.
