RSSBus (@rssbus) is promoting a "limited time offer - one per company" free 10-user site license for the RSSBus SharePoint Web Part. I don't know how long it will be available, but here is the link.
The timing of this offer is quite nice for me since I have started the blog post series "10 DIY SharePoint Web Parts".
