How much would you pay for a product made in the US vs China

Personally, it depends on the part.
For the most part I would have to say 50% more for an American made piece.
After that I really have to think about it.
Except for bearings. I won't buy Chinese bearings, period. I've had too many failures and fitment issues.
Chinese hammers or race drivers? Sure, no problem. Although I do notice hardness issues as compared to American equivalents.
Chinese jack stands? Sure. I would prefer an American floor jack, but you can't find them.
