I think you can find it for less than $50. I was going to buy this one which is $25 but has mixed reviews:

Plus if you buy from 7sage you get the PTs in convenient pdf form making it a sinch to print and reprint sections you are having particular difficulty with. I love being able to print a copy of a game whenever I feel like and have a fresh go at it.
