Sorry to be the bearer of bad news but if you are concerned about buying or using products from overseas you're in big trouble. If you insist on buying 100% made in USA, then get off the computer you are on right now (forign-made parts, you know)
Throw away your cell phone, home phone, pager, fax machine, TV, VCR, stereo, all your house appliances, your car (hell, even if you have an original Cobra, that POS was made in ENGLAND!)
your shoes and clothes, and walk naked (can't fly or take a bus or train, more forign parts) to Pennsylvania and buy a wagon from the Amish. That's about the only thing that I could even half-way gaurentee is 100% made in the USA. We are part of a global economy, like it or not.
Please don't shoot me, I'm just the messenger!
