I went to 3 different groups before I found the right "fit" for me. Now, it wasn't that I walked in and thought "this is it". There were enough things that I could accept, that I decided to come back. I do feel you need to go to one meeting a few times to get a feel for it.
I was a regular participant for about 4 months before I picked a sponsor. By that time, I had enough meetings under my belt to have a feel for the regulars. From listening to shares, and from talking to people afterwards, I was drawn to one particular person. I don't think it's something you need to rush.
