I agree, but there are some low-end DNS providers which have good services that give you more "domains" for less than what it costs with Route53. I use Route53 for a lot of my sites, but for tiny client sites (and personal stuff which has lots of domains), it's hard to beat $60 a year for 25 domains at DNSMadeEasy. That's less than half of what it costs to use AWS for the same number of zones. Granted, the price drops after those 25 on Route53, so if you have thousands of zones in one account, best to use Route53. Just as an example of an edge case.
