I remember when I first learned about the Lagrangian, and my mind was blown that really complicated problems could be wrangled so easily. Thanks for sharing this :)

I learned from a less established text by Taylor: http://www.amazon.com/Classical-Mechanics-John-R-Taylor/dp/1...
Looks unavailable, but a PDF is very clearly the second result on Google for "Classical Mechanics Taylor" so it may be a good option for the tight budget :)
