I was wondering if this TV is worth getting and worth the price? I watch mostly cable TV so I was wondering if this is the TV for me. I have read some peoples post about blue tints in the corners and yellow strips across the screen and wanted to know if this was the norm. Will the XBR450 be better? Does anyone have any other request that would be best for my viewing situation? I just want to make sure before I spend 2500 bucks. Thank you.
