I love Dave Ramsey. He helped us turn our finances around completely and helped us get out of debt and start saving money. I also love that he emphasizes that he is very motivated to helping others.
Add about Suze Orman--I really enjoyed her books and thought she was great but then she had this dumb segment, "can you afford this?" and she was telling people they couldn't afford things like a guitar or a vacation, and they had 500000 in the bank.
