There are a lot of ways to look at it: If the cost is having that much impact on you, then there is a chance that your expectations for what you get for that price would far exceed what will be provided, so in that case, you won't feel that it is a good value. Also, if you pre-dispose yourself to disappointment, feeling remorseful about how much money you've spent, you could again set yourself up to feel that it isn't a good value. I recommend against both of those things.
Personally, I felt La Nouba was incredible, a great value for the money.
