I got the last 65" display model from my local BB/Magnolia. 6 weeks before even getting the check from Panasonic I ordered another 65" ZT from Magnolia (and paid for it in full) to ensure that I would get one before they all sold out. The night before my scheduled delivery the BB warehouse calls me to say that there was an issue - they didn't have any more 65" ZTs. So basically, BB sold my set out from under me, even though they had my money for nearly 2 months. worst part was, by this time, there were no more new sets anywhere else for a reasonalble price, let alone the $3000 that I had been refunded by Panny as a replacement cost (based upon my pending order with BB). I even called a day before to verify that they still had stock and that I'd be getting my set.
Luckily, my local BB still had their display model. It was in good shape despite the 3500 hours (and no box, manuals, remotes, or 3D glasses - no box really sucked how else do you ever move one of these things?) and they gave me a good price due to my scenario. Best part was I didn't need to run slides for weeks to break it in. I got to calibrate it right away. Fans are a touch loud (it was a May build), but I'm not touching this one considering how fragile these things are.
Nothing wrong with an F8500. With everything I went through with Panasonic, I was really tempted to go the Samsung route. I still might pick up a 60" for my family room if I can find a really good deal on one.
