Any Exerience with Unitarians?

I've had some dialog with somebody who has a small gathering of people (churchish), most of whom seem to be unitarians.  There is the belief that God is one person (unitarian), not three persons in one godhead (trinitarian).  They believe Jesus was a created being.  Apparently they are not also universalists.

Does anybody have any experience with unitarians?  Any special behaviors, or logical conclusions to unitarianism that are odd?  What is/was the fellowship like?  I know how to deal with it from a point of doctrine, I'm just looking for any others out there who have some history with the beliefs.  I know that trinitarians are not always - nor maybe even most of the time - consistent in their trinitarianism.  They don't follow trinitarianism through to practical conclusions.  I'm just wondering if the same thing exists with regard to unitarians.  Thanks for any help.
