Just got one last week from shoponkyo.com. I bought a refurb of the 705 for $475 shipped.
It was $499 w/ 10% off and I had some 'club onkyo points' I could use from registering other onkyo products that I had.
HDMI upconvert/pass through is a freaking wet dream. It makes everything so much easier when you can just plug everything into the receiver and then run one hdmi to the tv.
I'm only running 2 fronts and a center (all 3 polks) right now but it sounds really good. I had a tx-sr600 before and don't notice a large difference in audio quality but the feature set of the 705 is far far superior.
