@Norcky - All depends on wether you are happy to have a plasma with that 'feature' or not.
Do you find it offputing, or do you not really notice it? If it's a big problem, them get a refund and buy something else, maybe save up a bit more for a Panny or something
I had a similar choosing dilemma - buy a cheaper plasma just so I could have a Plasma, save up for a better model plasma or have no plasma at all
Went for the save up and get a better plasma (albeit at a good price

)
I asked the question
If you had a choice of getting a lower speck plasma (based on a lot of people opinions in this forum - LG, Samsung, Techwood etc) or no plasma till could afford decent one - what would you do?
My answer to that was no plasma till I could afford a decent one (again most people opinions Pioneer, Panny, Fujitsu, Hitachi(?) )
sorry for waffling
regards
