Hi, please can I ask for some advice? My local JL is selling a 'used' Samsung PS51D6900D for £795. It has no box or books, but has the remote. There are a few scratches on the stand. They have said that it is not an ex display model and it is return from online shop. If it was an ex display and has had 6 months heavy shop use do you would you buy it, or won't the useful life of the plasma tv be affected? Its only £100 less than online prices. I'm not sure that its such a great bargain. What do you guys/gals think? It has the JL 5 year guarantee included. No 3d glasses. Any advice would be appreciated.
