Hi, I recently bought my Sony Bravia 2 55S25 55" (non- B model).
Before buying this I did see x74l and x75l in showroom firsthand, I was unimpressed as Wide viewing angles gave a white hue to darker sector of the frames.
(I did ask the difference between my model and the 'B' variant with the showroom people, they said that the B uses a frame screen which also shows white Hue in dark sectors on wide angles & B variant is only available for online purchase)
I bought the TV from Kohinoor low-cost emi w/ instant cashback.
Effects cost became 57,500 (excluding 500 from old tv exchange cost)
+350/- bank processing charges
