Ballast Point's Sculpin sells for $16 a sixer here in San Diego, where it's brewed!!
I can only imagine what it costs once you get out of town. They're very proud of that beer I guess. I don't think it's that good.
I think Beer Smith has some import features that I don't have in ProMash.
BeerSmith is also currently supported by the developer, ProMash has not been updated in many years (not that it needs it).
