Isolating natlangs?

Of the two conlang projects I have going right now one
of them is mutating in the direction of becoming more
isolating.  However, I'm not at all familiar with
isolating languages as they occur in the wild, and I'd
love to look at the grammar for one or two examples.
I'd prefer languages that are at the more extreme end
of isolating.  Can anyone suggest a couple isolating
natlangs (for which grammars are readily available)
that I might take a look at for guidance and
inspiration?

Thanks,
