I prefer to get mine from the internet when and if possible.
Some of my friends have their friends and family hang banners up on their porch that link back to their sites, but I don't think that passes as much link juice as those from the web.
I'm just messing with you. Seriously though, the question you're asking has got to be one of the absolute most basic questions. This forum, every other IM forum and and a quick google search all will provide you with an endless list of quality answers to your question.
Put a bit of effort in, you'll get a lot more out, I assure you.
