The only time I seen barry post in this thread till now, was to say the ebay gun and the one matthew has is not the same, which you can tell if you compare the two. I don't see where you say he was promoting his business. He didn't say he got the gun for matt until he was specifically asked. In fact I see people often recommending his products and he doesn't get involved, unless someone has a particular question about use of that product. Now if someone would put the dang ebay cheapy or the other one to the test, can get back to the topic at hand.
