Equill brings up several good points (as usual). If you have a chance to test it before buying it, I strongly recommend turning it on and observing it for perhaps 30 minutes or so to see if it suffers from the infamous "tunnel vision" effect equill refers to. If the corners start to darken (and get progressively darker with time), you may wish to reconsider your purchase (or renegotiate the price). This problem is fixable only through replacement of the panel, so it's a big defect.
