Another vote for CoreOS's repo; it was how I _really_ loaded k8s into my head, because the vagrant setup is multi-machine but _local_ and thus one can see what's going on and destroy-recreate it at will.

I think one can choose which approach matches one's learning style, and I am very thankful we have both KTHW and coreos-kubernetes.
