‘Just’ HD Ready is old hat.
If you really care all that much about TV, 3D content doesn’t seem to be taking the market by storm glasses or not.
AFAIK HD ready means it can actually do 1080i (i.e. best picture).
EDIT: Had a brain fade, see above for HD ready/Full HD .. I bought Full HD as the difference wasn’t great in price
Is it worth it? If you intend on buying one with an HD tuner, or downlaod HD films, or have a PS3 or other Blueray player then I’d say so. As even the standrd 5 channels are offering HD over freeview, I think buying one with a Freeview HD tuner built in is a decent investment. Seems to be cheaper to buy it in the TV than as an add on box as well as neater.
I bought an LED (not LCD) LG 37″ with Freeview HD tuner from Amazon for £429 to replace my CRT – got a Amazon card for 9 months free credit and another tenner off. It’s very nice, but I’m not an enthusiast, just like to watch the odd film, series and stream stuff from the Mac.

£20 cheaper on BHSDirect but I don’t know what their terms are if any.
