Not all the ones you might choose based on scale support axfr... That's a bit of a problem for the most traditional approach to this., of those that do it's straight-forward to use one as the master for another, or use a hidden master. Your own master may have demonstrably lower availability then one or the other of your providers. getting two well considered choices to play nice with each other isn't that hard.
