www.ereader-store.de - shipping internationally and good price
I bought mine there and experienced great customer service. User "Booxtor" in this forum is the owner of that shop.
But there are more stores out there. I don't know them though. If you wait a day or two somebody will definitely name you another one.
EDIT: Oh I just noticed, the price of ereader-store.de is maybe not really the best one for you as a US customer, because the dollar-euro exchange rate is (in this case) not really in favor of the dollar prices
