Speaking of electronics:
ATI amplifiers are made in the USA . I have had one driving my home theater now for 13 years, flawlessly. It cannot be be over-driven. A great amp:

Unfortunately, my speakers (NHT) and subwoofers (Velodyne), which are excellent and were made in the USA , are now manufactured elsewhere, from what I understand. There are plenty of companies though that still make speakers and subwoofers in the USA .
My surround processor is supposedly designed in the USA (Outlaw Audio), and then manufactured elsewhere (China or Korea - not sure).
I also have a titanium frame road bike frame from the US, but all the components are Japanese. That's about it, though. I used to be very careful to find quality stuff that was made in the US, but it became too hard, and all my favorites (see above) decided they couldn't compete, either, so I just gave up.
