Pre-marital Counseling, is it worth it?

P and I are considering pre-marital counseling.  Now, don't get all freaked out and ask me what's wrong.  We are better than we've ever been, and SO ready to get married.  But I really believe in the value of pre-marital counseling when it is done right.  (If you are unconvinced, read this post.) 

The problem is, it has been really hard to find non-religious and affordable pre-marital counseling here in NOLA.  We went to two different people that I found through Internet searches for initial searches and they were just not right.   The first lady?  Creeper.  Seriously.  We left her place, took one look at each other, and we were both like, "no way".  The next one cancelled on us like four different times. 

We finally found someone who sounds like she has her sh*t together, and from talking to her over the phone it sounds like we would be compatible.  The problem?  She costs $65 a session.  Apparently this is cheap, but we are on budget here.  Especially since we just dipped into our savings to buy two expensive flights to Wisconsin on short notice.  I'm starting to think I will put my psychology major to good use and lead our pre-marital counseling sessions myself.  I kid, I kid. 

So, I'm asking y'all for advice.  Have you done it?  Is it worth it?  How many sessions do you need to go to in order to really make it "worth your while"?
