Yes, there were problems. But every time there is a new product launch, this forum is flooded with people having screen issues. It's hard to tell which complaints are legitimate and which are people being nitpicky. And in the end, it was not a widespread problem, because, as has been mentioned before, if it really were a widespread problem, a lot more people would be returning iPads, and instead of getting a thousand hits in google of people complaining on forums, we'd be getting a million hits of news articles over the latest Apple "screen-gate," or whatever the press decides to call it.
I'm sorry you had a bad experience with multiple iPads having the same defect. Perhaps there were indeed early batches that were defective. Perhaps your Best Buy got shipped a carton of a bad batch. To go back to your original question, yes, I think if you buy another iPad now, chances are good you'll get a good unit.
