Has anyone used "Made in Taiwan" lifters. I recently bought what were supposed to be American-made lifters. They showed up in a plain, brown box, with a "Made in Taiwan" label on the front. The advertised lifters were out of stock, so the seller substituted the Taiwan lifters. I could see nothing wrong with the quality, but I returned them, at seller's expense, and will receive a full refund. The seller has removed the ad. 

I have a line on NOS American-made lifters. Are there any American-made lifters that should be avoided? 

I don't necessarily believe that all off-shore products are bad, nor do I believe that all American-made products are good. I would, however, like to see more products made at home.
