I will have to say most new tvs that you find will be ntsc compatable,in fact I would say you would be very unlucky to find a tv that does not.
Some people,again very few ,actually see a screen flicker at 50 hz if your one of these a 100hz model will cure this
This tv I linked you to earlier would interest me as it comes with a dvd recorder (gotta be worth a min £100) and the total price is £299,it s says due soon but they will have them in,my tv was labeled this and I had to wait a few weeks but they sorted me out
