Springfield Sign vs. Duff Brewery or Volcano Lair

My fav. would be the Volcano Lair, because it looks awesone and Hank is cool. Duff Brewery looks kind of boring. And the sign, well, it does nothing really, the bonus probably isn't worth it (there are many, many ways to generate enoug money). OTOH there are rumors that there will be a promo sale on Volcano + Springfield Sign. So I'd wait a couple of days to get it.
BTW, I am facing he same descision, got some donuts from Gil's sale and trying to decide on what to spend them...
