Setting up a campaign takes seconds and you can specify text before and after the link as well as varying the anchor text and even the URLS.
I will write back here in a few weeks to let you know if the links help my rankings. I am targeting reasonable easy keywords at the moment, so I should not need to wait very long for results.
You can also use this tool to build links to your other profiles and web 2.0 properties, not just your websites. So, I will try this soon as well.
