Haven't spend tens of thousands, but I have a similar experience. I use pairnic.com for registration and dns. I don't know if their customer service is good or bad because I've never needed it, but I suspect it's excellent. I use fastmail.fm for both SMTP and IMAP. I've never needed their customer service, it just works. I don't use my gmail account, but I keep it in part for a backup SMTP, although I've seen gmail SMTP go down and I've never seen fastmail go down. I suppose they must have and I just wasn't doing anything active at the time.
