If it is to support a human I would tend to agree, but for desks etc. I have found local supplies (Canada) have declined in quality to such a degree they need the level of QA on arrival the Chinese ones do while costing 5-10x as much.

unfortunately the big box stores do not check quality. mcmaster which was pointed out above does and is a similar price. I am not sure about granger.
