Alternative to Lead Enforce

Hi,

Some of you may be aware of a site called LeadEnforce - they allow you to build Facebook remarketing audiences by scraping the members of groups you specify. The issue with their service is YOU don't own the audiences that are created and you only 'rent' them, the service is super expensive like $200+ a month - can anyone recommend any other tools to market to the members of chosen groups or an alternative to LeadEnforce?

I used em, they sucked

42matters used to be free but dont know how its currently

Does 42matters allow you to profile and create audiences based on Facebook groups you specify?
