I have a chance to buy this receiver for $400- The guys says he bought it for his brother online and never opened it- ??? Anyhow he says he will demo it for me to make sure that it works. I am worried that Onkyo will not honor the warranty!! I have read a few reviews. Some are really good, others say they have had major problems ( blowing up, lasting only a week or two) I want to get everyones advice!! Let me know what you think.
