Pro: It's not much trouble, DANE and other things will make it worthwhile, and it's easier to do when you can still have a bit of downtime without pain.

Contra: There's always much to do in a startup. Deferring tasks is good, even though they'll be more difficult later.

There are a few providers around who'll do most of the job for you. It's called a "hidden primary", and easydns offers it, among others.

Thanks for the comment. I'll look into EasyDNS and see what services they provide.

I may well take your advice and just go with a normal DNS deployment and then later on when I have more time make more of an effort to deploy DNSSEC.
