I've put monitoring onto my public website, and by far the largest component
of the response time it gives me is the DNS lookup -- 4-500ms, which seems
entirely unreasonable.

Is there a tool that anyone knows about that will measure the response time
of my zone servers, somewhere on the web?

Is the sum of the times in a dig +trace the proper metric to look at there?

Cheers,
