They tutorials here at SM are commendable. The instructor shows you the process on how to create the mesh, not just instructing you what to do in say video number 1 then showing you the finished model in video number two. And the steps are also explained so that you would know why he did that, so on and so forth. It's really a worthy investment all-in-all especially if you're just starting out.
