You don't have to go all the way to $1k+/yr to get much more piece of mind. For well under $100/yr, EasyDNS offers fantastic support.
My go-to example of their customer service philosophy: A number of years ago, there was some problem in the electric grid that resulted in power outages over most of the Eastern US and Canada. In response to just their customer service being unavailable for 1 hr during the much longer outage (their production services were unaffected), they offered me a partial refund without me even knowing what had happened. I didn't take it.
Usual disclaimer: Not affiliated with them in any way other than as a satisfied customer for more than a decade.
