Best Buy offers the Samsung 43" 600Hz 720p Plasma HD Television, model no. PN43F4500, for $299.99 with free shipping. (Sears has it for the same price via in-store pickup.) That ties last week's mention (which required in-store pickup) as the lowest price we've seen. (It's also a current low by $49.) Features include a 1024x768 (720p) resolution, 600Hz refresh rate, USB, and two HDMI inputs.
