Fry's Electronics offers the LG 50" 600Hz 720p Widescreen Plasma HD Television, model no. 50PN4500, for the in-cart price of $399. With free shipping, that's a buck under mention from last summer and the lowest total price we've seen. (It's also a current price low by $100.) It features a native resolution of 1024x768 (720p), USB, and two HDMI inputs.

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