"Some are good and some none of us know about."
That should have been your answer from the outset...
Funny thing, there's a bike shop back east - the owner of which who I know - who makes roughly the same statement as you - but appends it with the fact that those of which we do know tend to be re-labels wherever they are sold in the world - and wryly notes that credit for the good ones go to the seller - not the manufacturer...
Of course, this is old news...Schwinn comes to mind...
