I'm doing some part time classes in 3d animation to build up my portfolio for a full time program. I took the 3d max course and it was very good. They go over the basics in every section (modelling, texturing, lighting, animating, video post etc) so while you don't have anything great done after you finish, you do have some working knowledge to build on.
You really do have to take a class though. If you just try to use the program right off the bat, you'll make a sphere, twist it, bend it, delete it, then quit the program. There are so many menus/plugins/modifiers that you will be completely overwhelmed. Take an intro class, ask your teacher what program would be best for you to buy, and then go at it.
