How did you learn VBA

I just starting learning VBA in late May 2010. I've done some learning by reading (I only have 2 books and one is VBA for Access while the other is a small beginners manual). The core of my learning has been from recording macros and then incorporating the recordings into my own subs and; coming to this one forum on a daily basis. I've been planning on buying some advanced books for VBA but I don't which ones are good and which ones are bad. They are all expensive and I don't want to waste my money on something that will only be opened once.

Macro Recorder, Forums, Lots and Lots and Lots of Trial and Error (mainly error).
