Sony KDL46z4500 for £1100 with a five year guarentee. This TV was selling at £2000+ when it was first released earlier in the year. It is still selling for £1649 on the John Lewis website but JL High Wycombe have it on undersale at £1100 which is a fantastic price for a 200mhz Sony large screen.
There are newer models around but these are at least £1500+ so this slightly older model is definitely worth considering. Should be able to get any JL to match the High Wycombe price as it is unlikely to be displayed at this price anywhere else.
Can't find this cheaper - please correct me if this is wrong?
