Fry's Electronics offers the LG 50" 600Hz 1080p Plasma HD Television, model no. 50PN5300, for $479 with free shipping. That's tied with last month's mention as the best price we've seen for this TV. (It's a current price low by $61.) It features a 1920x1080 (1080p) native resolution, 600Hz refresh rate, USB, and two HDMI inputs.

Update: It's now available for in-store pickup only.
