If you're lucky enough to live near a Fry's, they have the Denon E-400 for $300. It's not coming up on their website so apparently, you have to go in one of their store to get the deal.
And how do I know it's the E-400 in their ad? I was in their store near Portland today and asked.
I called two stores here in houston. They both have them, but they want $575 for them (including the open boxes). They claim there is no sale on them right now and act like they never heard of such a thing. This was from a person working in that department.
