Local Business contact data?

Just wondering what people are using as a best software tool to get owner contact info for local businesses like the ones that come up on google places.

there seems to be a huge gap - plenty of software that scrapes "places" info and even public-facing emails like info@, but cant find any good tools that reliably mine data 1 level down to grab owner name/email.

All I seem to run across are all the LinkedIn based lead gen tools.

Any suggestions or recommendations?
