Dakota is Rutlands own brand. I'd question whether or not they are Chinese (like so much of the Dakota brand stuff) - then compare them to a respected seller of router bits who's products are proven but who's prices are MUCH lower than Trend - Wealden Tools http://www.wealdentool.net/index.html
I have never used the Dakota cutters, but can recommend the Perform ones from Axminster. I have a growing collection of them and am very pleased withe the results produced.
