Sony KDL-S32A12U or Toshiba 32WLT58 I`m about to buy one of these but not sure which. Sony`s website advises that the S32A has a `light sensor`.What does this do? Anyone know where I could get a online review? Have you bought it already? If so, whats it like? The Toshiba has 2 HDMI inputs and boasts a subwoofer output? My credit card is `at the ready - which one?
