Sierra Stitch era Universal

I read a thread on here a while ago (can't find it now) and someone mentioned the free digitizing software Sierra Stitch era Universal. I followed the offered link and read up about it. What I've read I like, but I haven't found a non-biased dealer yet so naturally everything I've heard and read so far is good. Has anyone here used it or are currently using it and what do you think?
