Coppernic is a good program, but Google is better in my opinion. The only thing I don't like about it is that it has a built in browser. I'd rather that it communicated back and fourth with my regular web browser which is IE 5.5 as a default. The other thing is the Coppernic never seems to find exactly what I am looking for when I use it. Google does.
WebFerret Pro is a great program too but the freeware version of WebFerret sucks. It's too bad the pro version doesn't have a trial version. I used WebFerret for years before they screwed it up by making changes in newer versions. I would actually buy WebFerret Pro if it were in a local computer store, but I don't like to buy software directly on the web.
