The company I'm buying my Plasma form has told me they now can't get hold of The Hitachi 42PD7200 and might be able to get hold of 7500. I have noticed on the technical info that both screens seem exactly the same, although the 7200 does say it has the New H4 Panel where as the 7500 doesn't. This seems the only difference other than the 7500 has built in digital and anologue tuners. Which is better? please help.
