ETA Programs

Has anyone here bought into ETA programs like Acquira, SMB DealHunterz, Regalis Capital, or others? I'm looking for insights regarding the support they provide beyond education:

deal sourcing,
deal structuring,
due diligence,
financing,
post-close transition and support

How effective are they? Did they help you accelerate and succeed in acquiring a biz? Are they worth the price of admission?

Thanks!
