It's no different with Media.
They do a lot of work for major manufacturers located in the US.
However, the one brand I made the comment about was made by another company that I can never spell correctly. Ironically at least two American manufacturers I'm pretty familiar with use them to sell product under their own name.
And you're correct, it all comes down to price point vs the engineering and quality control (along with printed information available) on the product that gets shipped in.
Sometimes I just wish they would have Americans write the installation manual. Manuals that come from overseas can leave you scratching your head due to the translation.
