I sell the Behringer mixers in the USA and also the Yamaha mixers. All of these mixers are made in China. I have sold hundreds of the small UB series mixers from Behringer and I haven't heard of a single problem from my customers. I have had no more problems with all the Behringer products I sell (and there's a ton of them!) then any other product line. You are also correct that the Mackie mixers are now made in China as well. It's all about keeping the cost down and being competitive with the competition.
