I share the same sentiments. It does not sound right when you spend months trying to convince the guys upstairs why we should switch to ArchiCad and then having to tell them we need to purchase an add-on to achieve better stairs.
I recently, but reluctantly, just purchased StairBuilder after reaching some dead ends with Stairmaker. I'm reasonably happy with the product, but feel that such an essential requirement to produce good staircases should be adequately covered by ArchiCad.
