I bought a TX-NR626 2.5 years ago, inspired by a Daily Woot but unable to afford it at the time I got it via Amazon as a factory refurb, so effectively the same deal and same gear. And it was a fantastic A/V receiver UNTIL the HDMI switch blowed up about two years after purchase. The cost of getting Onkyo to repair it was out of the question, it would have exceeded purchase price. I was able to get a local guy to repair it for about $120, the repair lasted for about 3 months and it popped again. Now it works as an HDMI switch, but it's not passing audio.
To conclude. I love the receiver: excellent sound, and when it was new to me, it was an excellent A/V switch. But I would hesitate to buy another refurb. I'm planning on buying another Onkyo, but it will be new, on sale, at Best Buy, with an extended warranty. I've dug in to the reviews pretty deep, and it looks like pretty much every brand run a risk of having the HDMI switch pop: it is, after all, a computer. I protect my gear as best I can by having it all plugged in to a UPS, but there's still a chance of something going *POOF* and the magic smoke escaping. That's just the way it is. But I'm not going to risk this particular piece of A/V gear to another factory refurb.
