Best 20" LCD Around $500-600

I've been looking for a new 20" LCD monitor, standard or widescreen, doesn't matter, but I've looked through so many reviews and forums that I'm starting to have a headache so I think the best thing would be to ask people who actually bought one and used it or just know enough about various models to give a good feedback. My spending budget would be around $500-600. I've read the reviews, so just let me know which ones you've had good luck with as far as overall performance and quality. Right now, I am thinking about the Acer F-20 but that one didn't get all that great of a review. Any feedback will be greatly appreciated. Thanks.
