Would you be willing to hire someone to monitor and keep one or more?
It would depend on cost efficiency. Would the amount of money saved by switching to a different provider be significantly more than the cost of hiring someone and paying them? Would it be better, cost-wise, to just add it to the responsibilities of someone who is already working for you, and who you already have confidence in, or just do it yourself? Think of how much you would have to pay the person per month, plus the cost of the hiring process, compared with the average cost savings per month by changing provider.
