Is there a way for Spotlight or Launchbar or Quicksilver or similar to just return matching folders not files?

Question

I frequently need to just get a finder window up that's a ton of folders deep.

There's only so many favorites you can put in the finder sidebar.

I'd happily configure a dedicated launcher to just get me to folders by name and use one of the others for their normal purpose.

I just can't figure out if any of them can be made to do this.
