Picked one up at my local Fry's tonight. Website shows shipping unavailable but multiple stores with stock. My location had at least 3 left.
Beats the Wal-Mart deal by a bit and you can at least inspect the box before you buy (the ones in store looked to be in good condition). They definitely aren't packed as well as a new TV, with bubble inserts rather than styrofoam, and it can flop around a bit if you tilt the box from side to side.
That said, mine seems fine so far, secret menu says it had 35 hours power-on time when I got it.
