Ask for the better Chinese one but with some replacement warranty (like 3 month), there are surely some available at a little higher price then normal Chinese ones.
I for myself got a Chinese one with 3 months replacement warranty in 2K. Chinese Axel set if starts working and does not trouble within first 200 Kms, then they will most probably last a long life just like other ones.
What they sale claiming Malaysian stuff, is also Chinese made, but of better build quality and some proper QC.
And the Genuine one sold here is without any sort of warranty. But they usually work fine if fitted accordingly and properly greased.
And I will not suggest for used ones, as this totally depends on the factor of your luck that day
