are definately something to take advantage of if you have the time and the money.  Some people can learn just from books and are very apt at being self taught and others really need some mentoring.  Even if you can learn well  on your own if you see someone else do a particular skill in the flesh, you're going to get it ten times faster.  There are also some home study courses that are excellent aswell.
