Sorry I go overboard sometimes. Did not mean to overwhelm you. Here I go again.
Fist please note that I work for Cornerstone and any recommendation that I make would be biased towards my products, so I make it a point never to recommend specific models or manufacturers. I have put together a monitor selector tool that may help you. See the following link.

Most people would agree that the tighter the dot pitch the better. The lower the convergence specs the better.
I always recommend at least 85Hz refresh rate at all resolutions you plan on using.
Resolution kind of depends on the monitor. Resolution is dependent upon the horizontal scan frequency of the monitor. Also there is a direct correlation between HSF and price. As the HSF goes up, the resolution capability goes up and so does the price. For example:
A monitor with a 70 - 85Khz HSF is optimized for 1024 x 768 at 85Hz
A monitor with a 92-97Khz HSF is optimized for 1280 x 1024 at 85Hz
A monitor with a 107 - 110Khz HSF is optimized for 1600 x 1200 at 85Hz
For the record, I use a Cornerstone p1700 running 1856 x 1392 at 85Hz on my primary machine, A Cornerstone p1460 running 1600 x 1200 at 85Hz on my development machine. And I have copies of almost all of the major brand models in my laboratory.
The reason I say that monitors vary is simple. Unlike many electronic devices, Monitor assembly and alignment is mostly a manual process. Since humans do most of the aligning, variation is inevitable. For example: The training of the operator adjusting convergence varies person to person. For the most part when you purchase a monitor or any other electronic device, what you are really buying is the company that sold it to you. What I mean by that is, No matter what brand you want to buy, call or e-mail the manufacturers and resellers tech support line before you give them your credit card number. First, time how long it takes you to reach a human. You don't want to sit on hold; you want to talk to knowledgeable people. Ask some basic questions about the monitor you are interested in. This will give you a good indication of the support you will get should something go wrong after the purchase.
Some sample questions:
Who makes the CRT in model # XYZ?
Even in branded products you may be very surprised to find out who manufactured the most important component of the monitor. This is the #1 way some manufacturers cut corners to cut cost. BTW I use Hitachi CRT's in all my products except my c910, it uses a Samsung CRT.
As I said before, what is the Convergence specification? Convergence is one of the most important aspects in determining the sharpness of the screen image.
How long is the warranty period? This can very by make and model. Some manufacturers offer 5 year warranties.
Do you have an extended warranty option? Companies with low confidence in their product line tend to charge higher prices for enhanced warranties.
Good Luck
