Hello all, I'm looking for some advice on these two plasma models. I'm having a hard time making a decision between the two, the 50PX50U and the 50PX500U. I have a deposit on the 50PX50U at a local dealer where I live with expected arrival in about a week. But I started to read up on the 50PX500U and now I'm starting to doubt my choice and lean towards the 00U. It seems I can get the 50PX500U online for about $200 more at an online-only store, but with a 3-4 week backorder. So my question is whether this model is worth the extra money and time over the lower model? What I was most attracted to about the 00U was that it was blacker than the other model and seems to just look better, appearance wise that is. There is then the downsides of not being able to return the tv to a store should any problems arise. And just to add a kink to my decision is the rumor I'm hearing that Panasonic is going to halt production of the 50PX500U and replace it with a different model??? So what do you guys think? Which would you do?
