Wall mount TV advice

So I've been doing tons of comparitive studies, and it just hit me ... just ask CF.net, problem solved ... so here I am.

Alright, so I'm in the market for a wall mountable TV, at least 40", only because LCD isn't out in 42" yet. I can't go bigger than that right now, both financially, and my living room isn't all that big either.

I keep hearing that the LCD is the future and that the technology is far superior to the plasma, but the price is also a good $1200 more. Mainly because the wall mount is not being offered free for the Sony Bravia 40" LCD.

I guess I don't really mind putting in the extra money, but want to know if it is really worth the extra money ... like will I really notice that much of a difference?

The choices right now are:

1) Sony Bravia 40" XBR model
2) Panasonic 42" TH-42PA30

Any advice or insight would be greatly appreciated!

Merci!
