First of all, a 15" monitor has nothing to do with a 19" monitor (See: NEC, which makes a host of crap smaller monitors.)
Likewise, a 19" monitor with defferent specs than this one has nothing to do with this monitor, either.
If you read the user reviews linked above -- and there are a lot of them -- you'll find them all over the map. Some people love it, some have had problems.
I think you have to look at it this way: This is the absolute cheapest 19" monitor you are going to find ANYWHERE. Add to that that it's a brand name, has a solid warranty, is from a reputable online retailer, and I don't see how you can't at least risk it (if you're in the market for a 19", that is).
