I used to use GraniteCanyon. But... I appreciate that the service is free and that they're volunteers, but GraniteCanyon just has unacceptable outages. Not necessarily downtime, but often DNS updates don't get propagated for weeks or months. Sometime around a year ago, their primary server had a disk crash and they didn't notice for two weeks. When the service goes down, the operators don't say anything -- you just sit in the dark and some day they come along and say, "Ok, it's working again."
I changed to centralinfo.net. They use some weird Win2000 DNS server (custom, not Microsoft's), and their forms easily let you produce a mangled RR file, but the service has been infinitely more reliable.
