In defense of Pioneer support, I would like to tell my story. I bought about 2 months ago the 84 that was a demo at a closing store sale for a very good price. After reading posts on avsforum, I found out it needed an upgrade since it was over a year old when I bought it. I called Pioneer, who told me to take it to a local repair place. They said it would take a day or so. I did so, and the next day they told me it needed 3 new boards and they were backordered for several months. I posted this on the forum, and was told to call the Pioneer rep. I did so, and she said she would look into it. She called back several days later, saying that the parts were indeed back ordered, and would not be available for at least a month; would it be ok if they sent me a new 94 instead! She said it would take a few weeks, since they have not received any yet.
It came yesterday and I have not yet hooked it up, but I wouldn't complain of Pioneer support again.
