Let me know if you find any reviews for that set. I too have been looking for reviews on that set.
I have found a few at bizrate.com for the 4215 model (same set just in black), and all six reviews gave the set 5 stars with the exception of one reviewer giving it a 4 star.
Let me know what you find, and I'll let you know what I find.
I'm extremely impressed with it so far. I'm about a month off from making my purchase, and it's between that set and the Hitachi 43". I considered the Toshiba 42", but the cabinet on that mother fell off the ugly tree and hit every branch on the way down.
