stokes2608:I have been offered an ex display Pioneer 9th gen for £1600 Im assured it was on for display for 3 months however 10 hours a day seems a lot should this put me off?
No, that's a very nice TV. However, plasmas do have a lifespan and that's a good few hundred hours already used. Use this, as-well-as the hassle you've been through, to haggle the price down further. If it has cosmetic marks then same again.
If you do go for it then be sure to make it absolutely clear that if you're not happy with it once set up at home, they will take it back and offer you a full refund. If not, then take the advice given by 6th.replicant above.
