Sony Grand WEGA KDF-42WE655 42-Inch LCD Projection Television with Integrated HDTV Tuner
One word - UNBELIEVABLE!!!
Updated:  2/22/09 - After nearly four years of owning this TV it still looks and works great!  No problems whatsoever.  Obviously this model is only 1080i but that is the best you can get with most cable and dish services anyway.  =================  I've had this unit for a few weeks now.  It is unbelievable!  The picture quality in HD and viewing DVD's is incredible.      The only frustration I have and this goes for ALL Sony products is the manual.  Their products are outstanding but the manuals that accompany them are very difficult to decipher unless you are a true audiophile.  After a few hours of tinkering around though I was able to get it all hooked up and the next day when my cable guy came out to install the HD box he made a few adjustments that got everything working.    My suggestion: If you are going to make this type of an investment including home audio and video equipment, spend a few hundred dollars extra and have a professional come out and hook it up.  I didn't do this but in hindsight I think it would have been worth it.    Once it's all hooked up and working the way you want it you won't believe the oooh's and aaah's you will get from this thing.  My father and father-in-law were in town over the weekend to watch NBA basketball.  Neither of them had ever seen an HD picture and both said it was better than actually being at the game.    Enjoy this product.  You won't be disappointed!
