www.mantisswords.com I have heard a few complaints against the Hanwei katanas.
I personally own a Mantis Banshee Sword, which I am pleased with. The scabbard isn't top notch, but I have not had any problems with the sword itself, and considering it's only $150 the quality was a bit better than I expected. It is sometimes classified as a Chinese broadsword, if that matters.
