I wrote up a guide here for buying/selling: http://ashleyknowles.net/2017/05/getting-started-with-ethereum-aussie-edition/
I got in nice and early with pocket money so I'm happy to wait this one out til it hits $2000. Quite confident with the backing Ethereum has, that it will actually get there - check out the Enterprise Ethereum Alliance to see who's on the list! https://entethalliance.org/
