I just ordered my 508 from the Dish Store yesterday and it should be here middle of next week. I can hardly wait!
By the way, did you notice that the language on the dishstore.com website is set to UK English? To ask the webmaster a question it asks you to make an "enquiry", and when you enter the expiration date on your credit card it asks for the "expiry date". Is the Dish Store located in Canada?
