Does anyone have any experience in triple p?

I've been looking for something to increase my expertise in the area and over the course of my 'careers' triple p has come up a few times. I know that it would help me in this field, and may extend my opportunities once I get back into the workforce (I know I'm not a lifer - I plan on working outside the home again once my kids are older).

I've been tempted to take some ECE courses as well, if anyone has any experience with either or both I'd really love to hear your opinion!
