I was in Manchester on business last week and popped in to buy some 3D3 3d glasses after they were recommended by strapped for cash.
T.P.S. are a Panasonic dealer , and even though that was all i was buying (the glasses), they took the time to chat about all things Home Cinema.
Even spent 30mins showing me the quality of the calibrated 60ZT65, it surely is a reference display. Made me wish I had a spare £3500.
If your based in the area and looking for anything Panasonic give these guys a visit.
As a footnote the 3D3 3d glasses are a step up from the Sony ones I use for my 55HX853, Thanks for the heads up strapped.
