it depends on how much you already know.

i suggest you first do the tuts provided with maya. and if you master the gui a bit, then it is time to spend money on other training material - but dont expect wonders, you still have to try it out yourself. so you can read as much as you want, and watch movies as much as you want, unless you do it in maya you never learn anything. if you happen to have maya 4.5, the video tuts are very good to get you started with the gui.


hope that gets you started
