Spring for the extra 40 bucks for this one. Unless you're going to be watching a lot of movies on a 10.4" 16:9 LCD. That thing from Amazon will look just awful without doing the chop top mod Al just mentioned. That ain't all that easy, I've got a box full of 5200 parts that I've cut up for such a mod and it's looking like it's too much bother for the final results.

800x600 is just about right for a 10" Monitor as far as I'm concerned and my ruler across the front bezel of the RGB agrees with the fit. Lay out a 10.4" diagonal 16:9 and it ain't gonna fit well side to side by my powers of guesstimation. [)] ]'>

I just looked at your second choice, 10.4" is a bit too big for the RGB to look right and that on is only 640x480. The one in the pic wins the contest handily from where I sit, RGB Bezel and yardstick in hand.

edit: I just checked your first choice again. I think they have the wrong picture up. The specs say 640x480 in two different places and the measurements for the product don't sound like 16:9. Lay it out on paper and see if the dimensions fit 4:3 or 16:9.

800x600 in a 10" Diagonal is probably worth the extra freight.
