depends on your definition of 'worth'.  

first question i'd ask:  
do you have the skills inhouse to manage this effectively?  
or will you need to employ (usually expensive) consultants, to maintain these
machines?

most ISPs don't charge for making DNS changes - if yours doesn't, and if
they're not doing too shabby a job of making sure your changes get done
timeously, i'd say let them manage it.
