Any good Social Bookmarking Software?

I'm looking for a Social Bookmarking software that I can buy. I'd prefer a software rather than a service because I'm on a budget. Also I'd prefer it to be somewhere under $100? But give me all your guys opinions. I'd love to hear them!

Thank you for your time!
