If you're looking for cheap, ecost is an option. Be aware however that they have a reputation for zero customer service.
I bought a refurb denon dvd 2900 from them a couple yrs ago for $550 and have had no problems. I recently bought a refurb onkyo reciever my folks from them and had to have it repaired locally before use- apparently they forgot to refurb the refurb. It was a minor repair and cost less than shipping, but there is risk...
You can save some healthy cash though.
