Like I said, it depends on the parts you buy. Obviously Chinese parts aren't going to be the parts you look for.
Finding anything else is a real challenge. For new ignition modules that don't come from Communist China, there's Hi Rev and FBO. For new '70 and later voltage regulators, there's one guy selling US made ones on eBay, and there's me. Or tracking down NOS parts. If anyone has other sources, feel free to share them.

The situation for HEI is currently somewhat better - I think that's partly due to volume and partly because you can't stuff a HEI full of sand.
