From your earlier posts I wasn't sure how much experience you had in Scientology. Since you spent four years in a squirrel group you definitely qualify as an Ex Scientologist. Congratulations!!Sorry, I meant 2015! I give up. [I've since edited the post.]
You're right about the prices; if memory serves, it was about £6,000 for OT3 in the mid-80s.
My position was a bit different; the CofS is supposed to be nice to you when you first join up and do introductory courses, but I had to deal with a forceful and abusive ethics officer who put me off the organisation. I also saw some of the more rigid and unpleasant things that went on, and decided I didn't want to get any further involved (I was also involved with another teaching at the time, which was lucky because I was able to use them as a reason to not go further that the CofS would accept).
About six months later, I decided I needed auditing and, not wanting to go back to the CofS, found an independent group where I spent most of the next four years. I actually took some persuading that the group was OK because of course the CofS courserooms had had warnings about "squirrels."
