Yeah, this is the nature of this hobby. If you look around and read the forums you will find a lot of useful information on what products to buy and not to buy. I had my wife get me the Accucell-6 for Xmas 2008 when I was just getting into the hobby, she bought it for $47 plus shipping coming from the US, but it was still $37 from Hong Kong. I am happy to see them come down in price, but at $50, it was still an incredibly good deal. It will put out 50 watts, so that is some major power if you are trying to charge Nicads and Nimh's and a good start when charging lipos.
Have Fun,
