Maybe a photog can chime in, but I don't think that $150-200 seems unreasonable since it was a free shoot. IF you had done a package it would be different, but he's gotta make his money somehow, ya know? So, if I could afford it, I would try to figure it out and purchase the CD. Basically for the reason that you said. I hate myself in photos like 95% of the time, but for some reason, I loved my BD photos. So I will totally reference them to feel good about myself in the future.
However, if you feel that $150-200 is too much (I would opt for the edited ones as well), then you should talk to the photog and let him know what you want and what you can pay and see if there is a happy medium you can meet at. He's in a service industry, so not saying he's going to screw himself, but he will want a happy customer that will refer others to him.
