It depends on what you are trying to do...

SSL certificates are not used in DNSSEC, so if you are talking about "to
deploy DNSSEC", then the answer is NO.

If you are trying to secure your http, pop, imap, etc. sessions, and a
self-signed certificate is not enough then yes, you need to buy a
"certificate"
