Hover has been about as no nonsense as it can get. Not the cheapest, but I'd rather pay a few extra dollars a year to not have to deal with this in the future. I swear I'm the only person I know not constantly switching domain registrars, because I don't want to waste time sweating over maybe tens of dollars a year for something so core to my operations.
The one time many years ago I had to call support for a question a human being answered in 2 rings.
Tucows (which owns Hover) has been around for 30 years. It's likely they'll be around for a long while still.
