Depends on what you want to get from the class and what that amount of money means to you.
For example, the violin class by Perlman that I took. Judging by the content alone, I wouldn't say it's worth $90, since it's not that deep, and a lot of the information is online for free already.
On the other hand, I can comfortably afford it. I'll happily pay that 90+ bucks just to hear Perlman talk about violin for a few hours, regardless of the depth.
I'd say the same for the writing courses. Not deep, no special secrets, not going to make you a master. But if you just want to hear them talk about their own crafts and processes, it's also a bearable price.
