Repmgr is relatively easy to setup and supports automatic failover with repmgrd. Resyncing a failed node is also just a few commands. The only limitation I have encountered was that I had to run it behind pgbouncer so the clients can always connect to the primary instance. I think that will change with 10 as it will support client side discovery of the primary node.
