Bishoujos are good for the price they release at. But when they get difficult to find and the price skyrockets, I don't think they're really worth paying triple-retail value, given the general quality of the sculpts when compared with figures put out by companies like Alter, Max Factory, or even other lines from Koto themselves. There are a few exceptions, but for the most part, the idea of paying $150 for a bishoujo is ridiculous. The one exception probably being Catwoman. If someone offered me a sealed Catwoman bishoujo for $150, I'd snap it up. That's how I feel about it. But on the other hand, with this hobby, a lot of value is placed on what you like and how much a figure is worth to you.
