The free Dell Spotlight Essentials provides information similar to the DPA Advisors for each instance, but much more comprehensive and detailed: Missing Indexes, Security Policies [Guest user and password policies], Best Practices [use of Select *, Optimization Hints, and Set Rowcount], Recovery Model, Backups, Ad Hoc Workload, Configuration [Compatibility Level], etc.
If I can get all that from a free product, I should be able to get that kind of analysis from DPA. I have a strong preference for not running multiple SQL monitoring tools, especially on production instances.
