I sincerely hope that's not the case anymore but that lasting first impression has stopped me from looking into it since then.
Getting up and running with OpenShift is pretty easy. You can either use the all in one Vagrant VM[1] or you can download the CLI[2] and run `oc cluster up`[3] to install the docker container version.
Either one doesn't give you an "HA" install (probably want a cluster for that). I regularly deliver OpenShift installs, and in most enterprise environments an HA install takes 3-4 weeks, most of which is communicating to all the silos (networking, storage, security, virtualization, etc) what the requirements are.
