Check this deal out at Onecall -- <a href=http://www.onecall.com/ProductDetails.aspx?sHist=12-127&menu=true&Sort=highPrice&Page=2&didRedirect=true&id=23876>Harman/Kardon DPR2005</a> for only $525, original list price $1,600. As the new HK AVR models come out in the next couple months, there should be more good deals. They've had the AVR 635 for $635, and will probably go lower soon.
If you still want to upgrade speakers, Audioadvisor is still offering free Wharfedale Evo-DFS bi-pole surround speakers (worth $500) with the <a href=http://www.audioadvisor.com/store/productdetail.asp?sku=WHARFE20B&product_name=Evolution%2020%20Floorstanding%20Speaker%20-%20Pair%20and%20FREE%20Pair%20Wharfdale%20DFS%20Surround%20Speakers>Wharfedale Evolution 20</a> for $999. I recently got the Evo-Center speaker for $200 on eBay, worth $500.
I lost a few bids last month on some nice Velodyne SPL subwoofers worth about $1,000 that went for under $500. I ended up with a Sunfire True Super Junior due to my space restrictions.
Good luck!
