I'm up to Congestion Charge City tomorrow, and have engineered some spare time. Where's the best place for me to view the latest plasmas where they'll have been properly set up? I'm assuming that the big stores (Selfridges, John Lewis, etc.) will be a bit clueless. Anyone any good experiences anywhere? PS: I'm mainly interested in seeing the difference between the normal and HD Pannys (42") with or without scalers, for Sky+ mostly. Pioneer MXE1 as well, I s'pose.
