Ordered mine online at Circuit City for $539 plus a Terk TV44 OTA antenna made for satellite dishes and did Express Pickup at the local CC. Got there and had the BestBuy.com price printed out and the phone number to the closest BB store in hand ... Guy looked it over 4 or 5 times not believing that the CC price could be $139 more than the BB price, but in the end he adjusted the price (he didn't call because he said the BB had caller ID and wouldn't pickup the phone ... haha)! Price before rebate: $385 after 110% PM. Price after $100 rebate, $285 + sales tax! Not a bad deal at all!
So far I've got the Terk TV44 antenna taped to my window, and I'm able to receive a few OTA HD channels, I figure once its up on the dish then it should be able to receive even more stations and receive them more reliably. I did read that this Hughes receiver runs very warm, and that active cooling by using a fan on top of the unit is recommended. A few users on avsforum.com noted that the active cooling helped them improve their OTA reception versus having no cooling at all.
