I had been wanting one for a long time and certainly couldn't justify the price of a 4520. The cheapest I had seen was a used unit for 1000.00 about 6 hours from me. I happened to click on Ebay at the right time and...voila. Apparently, this was a Newegg(I was surprised when the address led me to a Newegg warehouse) deal that someone returned when they found there was no warranty. The remotes still had there plastic, all the packing material and box. Not a scratch or any evidence it was even plugged in.. It works perfect and I'm stoked!!!!!!
