There are no US dealers. We all bought from overseas. US regs does have an overly liberal and often abused mail order return policy but it doesn't apply or can be enforced on overseas sellers.
When I bought an E11, I did so from a US vendor. Not because I could return it for a month but to have local service and representation. I resold it within that month as it was not the sellers fault that I thought it superfluous to my needs.
Did you just get here? You bought something that has had these very things discussed ad nauseum and they are not unlike the various quirks of other HiEnd players. Why would you buy one if this was going to be a a major issue for you? It is admittedly not for everyone but that's what Headfi threads like this are for, to reveal the idiosyncrasies and personal compatibility of a product. It's like folks read a thread with tunnel vision, buy one thing and than expect another.
I have an SD card that works in 2 of 3 Sansa players I own but not the 3rd. I don't blame the player. There is no problem with HiSound selling this player. There is a problem with you buying it. It's just not for you and there is nothing wrong with that but it should have been apparent before purchase.
