I had a 21.5" ViewSonic that I used for a year and it was very good as well. Not as aesthetically pleasing as the Samsung, but at the time it was a better bang for buck. If you get them cheap enough, they work just fine.
I agree... Right now I have this monitor.

Got it from a local store that had it in a special sale. Can't say enough, it's amazing. Especially when you upgrade from a 15" CRT
