I own the 42 inch Toshiba set, and out of all the TV's I have gone through exchanging and returning, I have finally found a keeper. This is a very good set, be aware though it has a glossy screen. As for the ms, Toshiba does not seem to give out the their true ms rating on their sets, this might be a 2 ms rating based on the sticker on the TV, I could be wrong though.
Put it is def lower than 8, I play fast paced FPS games and watch some heavy fast moving action movies (Blu - ray) and have not seen the slightest blur (unless the effect is intentional.) Great TV for the money, though the A650 is a great set as well based on reviews and what I have read on it....it's a 08 model though I am not sure if 2k is a good deal, i think the B650 is even cheaper at that size...I could be wrong though.
