TH-37PX8B and th-37px80 whats the difference?

[admin_exported]

just looking for a friend, apart from the price, what difference will i notice between the 2, looked on pana website. and apart from the contrast all seem the same, is it worth the extra for the 80

I'd have to recheck, but I believe theres an extra hdmi socket too yes?
