Man that's a tough question!

My $0.02 is this... think about how long you expect the tv to provide service. If it's say 15 years, then divide the total price by that. If it's lower you get the idea... Secondly, what sort of picture quality do you want? While you'll be hard pressed to see a difference between 1080i and 1080p, having a little extra protects your investment with regards to upcoming technology.

Remember tv's aren't really a disposable asset like computers and cars are to people. Pay for quality now and enjoy the experience of your decision throughout the process. I'm saying this because after months of thinking it over, I bought my dream 46" Sony XBR2.

Good luck and I hope this helped!!
