(1) Where did you guys buy your 833? Without going into specific prices, I can pick one up on Ebay for a lot less than my local BB, after considering delivery prices vs sales tax, etc. Does Mits honor the warranty if you don't buy from an authorized dealer? The partial warranty they have on their web site doesn't say. What do you think about extended warranties (regardless of where you buy the set)?
(2) Seating distance - I now sit just under eight feet from my six year old Sony 61" TV. This is the bulky old style that weighs around 800 pounds
The HDTV picture on that set is 55", or about 18 inches smaller than the 75833 (I would prefer to not get the 65833). The front of my old Sony is 36" from the wall, allowing a little room for wiring. It is about 23" deep. So, I would gain 6 inches compared to the 75833, which is 17" deep, plus I could move it back a little bit. I would end up sitting about 8'8" from the 75833. Do you think that is too close?
BTW, I just bought my daughter the WD-65733. She really likes her new TV. How different is the 833 series?
