Have to say - we had a great experience with them. It took 2 months longer than expected to form the group, but it was tremendously helpful. One thing to keep in mind is that none of these groups can give a quick fix - they teach short term tools and long term strategies, and it requires work and practice outside of group. Don't expect to go and have your child be "fixed' by the time it's done. If you practice, you'll see improvement. We also had a great group of parents in the associated parents-group, but I've heard that's not always the case.
