Amen to that. My GM HEI was made in Taiwan, if I recall correctly. One reason I wanted it was for its melonized gear since I was installing roller cam. I thought a GM distributor would be solid, but I guess not now that I've replaced the coil and module in about a year. DUI is based in Memphis:

While on the subject, here's a handy spark checker I picked up from Harbor Freight for only $3.99 - a lot cheaper than the parts stores.
