I finally pulled the trigger on this tv. I have looked on every website there is and the hardest part is finding an authorized dealer with a low price. I payed $1684 ($1825 shipped with tax and the stupid $10 E waste fee). Amazon (through Pauls TV) has the best price. They will price match an authorized seller only. Pauls tv site has a "closeout price" on them right when you go to their page but amazons is cheaper. Not sure how that works since it is through pauls tv.?.. Anyways, they will not budge on the price even a dollar and I even tried to get a cheap-o hdmi cable thrown in but they weren't having it. I have noticed that the price has been dropping on the weekends. At one point, it was down to $1654 but I wasn't fast enough to save the $30 or so dollars.
The word is that these will be out of stock soon so I just went for it. Beats paying nearly double for the st50s with only minor improvements. They also offer a 30 day price protection even if their own price falls. Also, if you can use an American express card, you get an additional 1 year warranty on it too. I worked with John and he was a pretty cool guy. The price jumped UP while I was placing my order so you have to keep an eye on it and act fast.
