Could somebody please help a tight, worrying fool who has deliberated over purchasing a plasma for the last 3 years. What is the difference with the 7 series compared with the 6 series, on the specs list there doesn't seem much difference. I am thinking of going for a panasonic and I would save a couple of hunred squid if I went for the 6 series. However would I be better paying the extra notes for the 7. Cheers.
