noob tv question

[JayKay]

So while 1080p is supposed to be the best you can get right now, what is the difference between these 3 tv's? They *all* claim 1080p and a contrast ratio of 7000:1, but they differ in price by as much as $900.00. They're all the same brand (Sony Bravia 40" LCD).

The only difference I can see is that the first two have 3 hdmi inputs while the last has 2 inputs. Not sure if that is enough to warrant the price difference in addition to the fact the first two are still different in price despite having the same number of hdmi inputs.

The biggest difference I see is that the third one (Sony KDL-40V2500) has a Native resolution of 1920x1080 (or at least the claim on "Native 1080p" indicates this. This implies that the other two don't have it and so must rescale the image down.
