Seems like a pretty good deal for a decent TV — Not nearly as good as the 900A but hey, it's half the price. Has been on sale around $1450 before, the lowest price before on OzB was a Bing Lee deal at $1350. Currently $1700 at JB pre-haggle, and $1500 on BigBrownBox.
One unique selling point over a comparable TV (say a Series 6 Samsung) is that it makes an excellent TV for gaming — the input lag on Sony's 800A and 900A series is less than half most other TVs (covered by both reviews below…)
