Well, flat widescreen TV's that have a HDMI input are getting cheaper by the day...
Certainly if you let go of hype items like 3D and 'Smart TV' (meaning it is a bit like a tablet PC accessing the internet or a DNLA device like your PC), screen size and brand (Sony and JVC are notoriously expensive and LG and Samsung are usually the cheapest over here) determine price. Here, a 40" widescreen TV retails around 400 euro the cheapest, which is
including local sales tax. Of course I do not know your household priorities...
