Can’t think of what to get for Father’s Day? Sony’s 3D Blue-ray Home Theater System sounds like a fail-safe idea, what with the option to connect it to an Internet browser, more than 15 Bravia Internet Video channels, a built-in Blue-ray player and a state-of-the-art surround-sound system that could blow the roof off. $699 from Sony Style, #04-36/37/38 Paragon, 290 Orchard Rd., 6738-7970.
