The only good reasons I can think of is if the ISP/Registrar provides
very poor service or, if you need some kind of special handling. I do
this in my day job since we manage multiple domains, and occasionally
have to do things like adjust TTL because of a pending change, that
kind of thing. Or setup a temporary subdomain. I keep a terminal open
to our main DNS server, and can make any change live in 60 seconds.
No sweat, no mess. Overall, I'd prefer somebody else do it. If I had a
few domains and changes were very infrequent, I don't think it makes
sense to do it yourself. Well, maybe as a learning exercise, or
something like that.

Ideally, yes, of course. At least two. Hosting on one system is just
asking for trouble.
