I bought a piece of home entertainment gear at a car-boot sale, but no manual. I tried manufacturer's website, but could not find the particular model (it was about 5 years old). I then tried 2 search engines, and got 5 websites that sell such manuals for $9.99 Then I stumbled across one
formatting link
which had free links to manufacturer's download. So the spivs who want my credit card number lost out!
