I'd definitely recommend an ABA breastfeeding education class. You will receive an ABA membership with the cost of the class. Membership is $65 on it's own so you end up paying just $20 or 30 I think for the class, really, if you look at it like that!

A lot of people don't think about what happens after the birth - the BEC is a really great way to focus beyond the birth on what happens when you get home!

As for antenatal classes, I just did the hospital one. It was ok, but if I didn't have the internet, bellybelly and a bit of research under my belt, it would not have been enough, IMHO. I'd look at something else, like L&B mentions above.
