If I were you, I would do my best to either go to a Financial Peace University or order the kit to do it at home. Here's why:
I have been a fan of Dave Ramsey for a few years. I started listening to his radio show until the station stopped carrying it.
I wanted to start so I got the the TMM book. We read it. While DH is not a big spender, and could save cash like crazy, I am the one who wanted to do it but couldn't quite commit all the way so we didn't do it.
We are in our 4th week of Financial Peace University @ our church. My DH was skeptical about spending the $100 to do it (my lack of commitment), but is now soooo into it! We have all of the budgets, allocations, etc. and we are now starting our debt snowball. Just by telling our money what to do, instead of our money telling us, he feels so liberated! While I have committed to doing it, I still feel nervous about it, like I might fail.
It is different doing FPU as apposed to doing TMM by itself. I'm sure it has been done, but just listening to DR he really makes you think about things.
If you can only afford the TMM book, then by all means, at least do that. In fact, I think I saw that all of his books were $10 right now.
