I wish Panasonic sold OLED TVs. I've got one and at least when this was released, it had the best picture quality out of the majors (LG, and Sony).
Now though, LG have upped their game, but I think Sony OLEDs are slightly better. If I was buying now, I'd be looking at one of these:

And just something to remember, Leon... when you see TVs in a store, the store is massively bumping up contrast and saturation to "wow" their customers. At home, you'd never ever run your TV under those settings, otherwise you might as well get a cheap LCD.
