Converting from IPB - blogs

I'm giving some serious thought to switching a site to XF from IPB 3.4. My current IPB set-up includes blogs and I want to bring these across.
I know XF does not come with a blogging platform. However I saw reference on the forums to third-party blog add-ons with importers. I can't find those though - any ideas?
I have had a look through the resources, but can't spot anything useful - which isn't too surprising, there probably isn't much demand.
