I have used https://pair.com https://pair.com (or their domains side: pairnic.com which now seems to redirect to https://pairdomains.com https://pairdomains.com) since about 1994 and they have always been reasonably low-priced (I think it was $8-10 up front then ~$1/month for a domain) and they have always provided good support, clear policies, good documentation, and zero nonsense. I.e., just what I would want from a sustainable business that treats others the way they would want to be treated. (Same goes for their ubuntu or FreeBSD shell accounts and site hosting, etc.) (ps: they are in the USA: Pittsburgh Pennsylvania, and maybe Nevada?)
