The nice thing about a self help group is that you get a free place to meet like a therapist office or church, ect then there are no or low costs. Usually 12 step groups if you go SIA or ISA have small rental fees, usually in churches, or just donations to the church.
Sometimes a therapy group with a therapist is not right, you have te group dinamics, and the treapist too, the person joining that group must fit into the group. There is a lot to being in a group. Right now my current group is doing well. I am glad for that, but not for all the driving, wish I wasn't all over the state.
