I agree with whomever said: what is the class worth to you? What is she teaching and how many students? I have paid that much for hands on class from a LA teacher at a Quilt show (Road 2 California), but never at a guild or a store. I just had a class with Wendy Mathson (Storm at Sea) through one of the guilds I belong to and it was only $35. She even brought her templates for us to try, rather than us having to buy them first.
I had a class with Paula Nadelstern at my LQS a few years ago and it was about $75 (?).
