Inexpensive, take a look at these Acers:
I have not seen these personally, but they are cheap. Check the mfg page for specs. The contrast ratio and viewing angles aren't as good as say, a Samsung 710N/710N-2, but the Samsungs are more expensive.
I would stay away from anything ViewSonic. They lie about their specs and while they may produce one or two good monitors or lcds, usually you will not find them locally and most people will settle for a cheaper, similar looking version, which is usually beyond horrible.
Now about the 1280x1024 resolution. Yes, it's not 4:3, it's actually 1:STUPID. That's right 1:STUPID. I just made that up. 17" LCDs suck for two reasons. Actually three (pardon the haste):
1 - It's an LCD.
2 - None standard aspect ratio. True, it won't display a circle like an ellipse (egg on its side) because as one poster pointed out, it's slightly more square (longer) than a CRT or 15" LCD (relatively speaking). Nevertheless, this doesn't help matters because LCDs have a crappy vertical viewing angle which means you will be raising your neck if you want to view "hidden detail" in dark images due to the also shi$#y contrast ratio. Horizontal viewing angle is also bad, but not as noticeable as vertical (like all LCDs).
3 - 1280x1024 is too high because a) since it's an LCD the contrast ratio blows, meaning you will have to turn up brightness to compensate and burn your eyes out, or you will have to view the LCD from a distance, which means you will not only ruin your vision, but also increase your eye wrinkles by a factor of two, I suppose, because you will be constantly squinting.
Here's how I think LCD's resolution should be laid out:
15" - 1024x768 4:3, just as they are
17" - 1152x864 4:3
18" - 1280x1024 with a 4:3 physical dimension so all those weirdoes who run their CRTs at 1280x1024 won't notice a difference
18" for normal people - 1152x864 or 1280x960, I can't make up my mind
19" - 1280x960
21" - Ban these, you will go blind
As far as I'm concerned, LCDs are for consumers who use their computers for two hours every other day starting at 6PM to browse the Internet. Yes, they are dazzling to look at, at first. But there are simply too many disadvantages, especially for business and games.
Summary: LCDs suck.
I own a 17" LCD btw.
