Self Managment vs Paid Strata Manager

Our NSW Strata Scheme has had two different Strata Managers in 2 years. We have not been pleased with either. It seems that the advice they give us is not in compliance with the Act, and even the election of our last Strata Committee was not in compliance which we pointed out to the Strata Manager but was ignored. 

Has anyone moved from paying a Strata Manager to self Managment by the Strata Committee and if so what were the pros and cons?  We are a 14 lot Strata Scheme.
