B&K avr307

I was thinking about buying a new receiver for my surround sound system. My current receiver just retired. So was at the store tonight. I was checking out the Yamahas, Onkyos, and Harmon Kardons. I saw a B&K avr507, when the salesperson described the features I was overwhelmed. I really liked the idea of being able to upgrade the unit off the internet. I can't really afford the 507, but see the 307 used in my price range. I checked out the reviews on audio reviews.
Are these receivers as good as I was told my this salesperson? Anyone owners out here, might be able to add anything? Comments suggestions?

Thanks to all that reply!
