If you aren't trying to do anything too complicated, it might be good to use, but there are various things I need it to do which it can't currently. Shader features aren't fully implemented for example. You can't edit geometry or create custom geometry from vertices, etc. You can only load .obj models or three.js json models. There are various other things that aren't implemented. So, I wouldn't rely on it to completely handle every situation. That being said, I think it is worth the $30, since it can do a lot already. Hopefully we can get more updates for it to round out the features more.
