For $350 delivered, after a $100 rebate, you can get a Princeton LCD19D 19" LCD from Newegg.
It's beautiful, and it has a 8-bit per pixel color, whereas the 714 only has 6-bit per pixel color. That means the 714 has to "interpolate" many colors.
The main advantage of the 714 is that it has a faster refresh rate (due to 6-bit color), which is only beneficial to people who play fast games. If you aren't in that group, then you would be better off with a slower refresh rate and better color rendering.
If you can't afford the LCD19D, then keep looking for a better deal on a 17" monitor.
One nice thing about the LCD monitors is that you can comfortably pull them right up next to your keyboard.
I highly recommend a 19" LCD if you can afford it. Heck, it'll probably last for many years, so the extra cost per year will be very small. And if you get a 17", you may have a tough time justifying the switch to a 19", even though you'll know you want one bad.
