If buying new keep an eye on slickdeals.net or woot.com for deals like this:

Per prior posts you can easily ad BT audio via a Logitech unit like the one I have on my garage system:

Personally I prefer buying used higher end stuff at a deep discount versus the brand new feature laden units with stuff I will never use, got a NAD 773 off of ebay a couple of months back for $205 delivered, it sounds 1000% better than the Sony that it replaced.
