As has been pointed out here by others there are a host of things that can go south when buying an item on ebay from Japan. I have bought and sold on ebay many times and audiogon and us audiomart. Also bought items from Japan, Russia, Japan, Poland and China. Usually bought from a dealer when purchased overseas. Good deals and bad ones. Warranty has not been an issue as much as just reliable quality repairs. I would not want to ship a preamp and amp back to japan. I am glad the OP is thinking about these things.
