Pretty much anything that's $150 in that size will look terrible at any viewing angle but straight on--they universally use TN panels.

for a good 24" monitor, you're looking at ~$5-600. Cheaper to buy a TV--I think those have better viewing angles. I could be wrong.

If you want to drop that much on a monitor, I really like my HP LP2475w. Dell Ultrasharp monitors are generally well regarded, too, but sometimes they still have the terrible TN panels.
