I just got mine today, at $125 after coupon. I got a little worried because the material packaged with it says E770p, but the label on the back of the monitor says M781P. I'm not sure if the E770 is better or worse, but I got what I paid for
Cosmeticly (sp) it looks fine, and the sticker on the back says May 2000, so it's not that old. Heck, it's newer than my old Nokia 447L it's replacing.
I haven't done any in-depth testing, but the picture looks crisp, colors are good, averall better picture quality than the Nokia. It's running at 800x600 at 85Hz.
Only problem was a high-pitched whine (leaking capacitor?) when I first powered it up, but that went away as soon as Windows started.
Overall I'm very pleased with the purchase.
