The TV I own was bough used from a friend of a friend. Also do you know of any computers that are entirely made in North America, chips, memory, drives, and processor included?

Believe me, if there were viable options for US-made products for all those you listed, I'd consider them.

Anyway, I wasn't PREACHING, and I certainly didn't tell anyone to throw away their non US-made electronics. That would be wasteful and environmentally unfriendly .
