John, if the unit you are looking at is around $300, it is a copy made in hong kong. Real otal's run in the $1000 price range. I think the unit you are looking at on ebay is from the guy who imports the copies. He had one advertised here as well. Specifically ask where and by whom it is made. I have not tried this item, I was going to grab one on an auction at around $100 to try, but the price got bid up. I did talk to another guy wo was bidding on one who was getting a second, as he was happy with his first. IMHO, I would guess it is better than nothing and fairly functional, but a big step down from real production ones. Chris
