Yeah, penny stocks scare a lot of people. Has Steve Heller taken a close look at Sigma Labs (from what I can tell, he has not, or at least not written about it)? He could have answered that question in essentially two ways. The way he did, or an answer with some meaning such as I have/have not looked at them and I think they are good/bad for the following reasons. I'm assuming he doesn't know much about Sigma, so he took the easy way out, saying penny stocks are scary.
