After weeks (months actually) of studying and decision making, I'm pretty certain I'd like to get the 50-inch Panasonic TH-50PX50U Plasma TV. The problem is that I'm having trouble finding this TV in stock anywhere, whether online or in physical stores. I'd like to order online to save money, but I don't know what online retailers are reputable other than some of the well-knowns like Amazon or Circuit City, etc. Can anybody direct me to reliable online retailers that currently have this model in stock? As I shopped around and researched numerous TV types and models, I wondered if the most problematic thing might end up being just finding the thing somewhere to buy. Any help or advice? Any would be greatly appreciated. Thanks!
