I'd pick the specifications I want before searching for monitors. I assume your 17" did 1024x768 or 1280x1024. You want at least 75 Hz to minimize eyestrain if you're sticking with a CRT. If you want something similar, then you should be able to find a good one for a very low price - certainly less than $150. Some (of unknown quality) are under $100.

With the specs in mind, check out [link|http://www.newegg.com/app/ViewProduct.asp?catalog=19&DEPA=1&submit=property&mfrcode=0&propertycodevalue=3792|newegg]'s selection of 17" boxes. Many have reviews there. As with any review, you have to take things with a grain of salt, but it gives you an idea of how happy people are with them and what brands people like and why.

If you find a box that looks reasonable, go to the manufacturer's website. They often have pointers to reviews longer and more detailed reviews and comparisons.

Since the price for shipping of a monitor can be quite high, try to buy locally if you can. It'll also give you an opportunity to see what it looks like (but usually you can't change the resolution in the demos...).

Hope this helps.

Cheers,
Scott.
