I had a rolling machine but it was annoying as hell. It kept exploding at my face. I guess I kept doing it wrong, but even when I did it right it's just not the same as making a really good one with your own hands instead of just using a machine to do it.
Believe me, there WILL be moments when you don't have your roller with you. Been there done that.
Imagine making those perfect euro joints but with your own hands. That's mad pride.
