I'm pretty excited about receiving my 51H84C next month, I tell you - waiting is the hardest part! It's my first HDTV purchase, replacing the 6 year old 32" Trinitron. I got a great deal on the set, you have to love the shops which retail match prices.
Many hours of research on this site among others steered me away from a GWIII purchase (although they do look sexy). I'd probably have ended up with a Hitachi S500 if they weren't over $1000 more, but I'm sure it's for the better as I hear the stretch modes on the Toshiba's are very nice.
September can't come soon enough
