My understanding is that the refurbs from harmon come with full warranty. I would go for it myself. I have an older HK it is very nice, never a problem and the manual is very well written and clear. Just keep it handy, it is not intuitive unless they have changed from the AV310. I would swear by HK even today. I have both HT and 2 channel HK. The 2 channel is 15 years old and is still cranking it out.
