How to stop stuttering and love speaking OR Stop stuttering short course? Which should I buy?

How to stop stuttering and love speaking OR Stop stuttering short course? Which should I buy? Hey! Long story short, i'm interested in Lee Lovet's method and I want to give it a try! For those who have read one (or both) of his books, ¿which do you recommend? I think I'll go for Stop stuttering short course, because is cheaper hahaha Also, ¿Do you know if there is a Spanish version, or it's only available in English? Thanks in advance!
