Remember that you won't get any performance improvements by having the same brand of blu-ray player. The only advantage is Viera Link, so you can operate all your equipment with one remote.
But if you go for a Pioneer BDP-330 (42 cm) with a universal remote (if you want one remote for all), you won't need to buy new furniture.
The best price currently is £125. It was selling for £300 at launch.
