Hi there. I'm looking at either the Hitachi 42PD700 or the Pioneer 436XDe [depends if I can stretch my budget that far]. But rather than ask for everyones opinions, I'd like to know where would be the best place to demo these TVs and what type of questions should I ask in store? - bit of a noob to this you see. I know people on here say that Comet, Dixons etc aren't the best places, as usually their plasmas aren't set up very well, so where would you go to get a decent demo? Thanks.
