I think the negative comments about Behringer are, in general, grossly unfair.
Most products are 'copied' to some extent from other products in a competing field; when a new car is released by, say, Ford, Honda will buy on and tear it down to see what production techniques Ford use (and, believe me, it works vice-versa as well) and then determine how much profit Ford might make on it. In many cases the competing manufacturer may then look at adopting that production technique if it would lead to a competitive advantage.
Innovation is great - but then, frankly, quite a lot of Behringer products are innovative. The BCF/BCR control surfaces, for instance. Sure, there were other control surfaces prior to those, but look at the price vs capabilities of these products, and they clearly weren't 'ripped off'; they are engineered from scratch.
Since most US companies also use Chinese labour, I don't think we can fault Behringer for that. And if their after-sales service is not the greatest (haven't needed it, to be honest), that's a complaint that could be placed at the door of many an 'innovative' company.
I own two Behringer mixers, both of which have behaved flawlessly, and a BCR2000, which also has worked perfectly. I really do not believe that, in general, their products are inferior in design and quality, and I note that a lot of serious professionals quietly use Behringer gear without necessarily making a big fuss about it - it does, in general, do what it says on the tin. (e.g the UB2442 mixer. Show me a competing desk with those features at anything less than twice the price.....)
