Walmart offers the Samsung 51" 600Hz 720p Plasma HD Television, model no. PN51F4500BFXZA, for $348. Opt for in-store pickup to avoid the $44.97 shipping surcharge. That's $52 under last month's mention and the lowest total price we've seen for a new unit. (It's also $173 below the lowest shipped price we could find elsewhere.) Features include 720p resolution, 600Hz subfield motion, USB, and two HDMI inputs.
