http://www.opendns.commade my internet a bit faster, and was a piece of piss to set up.
you can make shortcuts too, for example type 'hg' in to the address bar and it'll bring you here.
if you want content control you can set that up as well.
its free, only trade off i can see is that if you misspell a url you'll go to an open dns suggestion page.
give it a bash, you can always revert to your default settings
