Why do you say "self hosting wordpress is a nightmare" ? I've been doing that for 12 years and have had no worries at all. Admittedly it's only a very low trafficked site, but still, curious.
I set up one of the orgs I work with on WPEngine, pretty good. Almost no intervention on my part and only $25 a month which is not bad considering the scale of there subscription business.
I do like WordPress though
