I could not agree with this article more. On the point about reaching out to angel networks for lawyer referrals, being on the lookout for conflicts of interest is an important point.

For many lawyers/firms (including many of the most well-known names out there), professional investors are a source of regular, repeat business. Some of those lawyers/firms may be (even unintentionally) guarded in their legal counsel to startups, so as not to take positions that will anger professional investors.
