What size you looking for (keeping in mind 99.99% are all wide screen now)?
1080P resolution 24" widescreens on the cheap end can be had at newegg for $120ish.
I've seen and used a lot of monitors. Everything from high-end calibrated IPS panels to the cheapy TN and TFT's. Unless you have a specific need for a high end IPS panel, the TN and TFT's work just as well for home users. I honestly can't find the difference between a $100 monitor and a $200, other than the $200 might have USB and speakers or other connection things that I never use.
I just bought a 22" ASUS last week on newegg for $99 (http://www.newegg.com/Product/Product.aspx?Item=N82E16824236100) so I have a dual screen set up. It's bright, good saturation, no dead pixels. In fact, I like it so much better than the older Dell 22" it is paired with, I'm buying another so the screens match (The Asus is so much brighter and nicer looking, can't get the screens to match and it's irritating).
Would love to get a pair of 24's, but I couldn't fit them on my desk, so 22's it is...and those just barely fit, lol.
