I think Ramsey's priciple's are great! Having a plan helped me immensly, and I don't subscribe to the thought that I am somehow not smart, or part of the 95% or unsophisticated because I find value in paying off my personal debt...the reality is right now I pay out $878 per month in personal debt service, plus $1,378 in morgage & PITI. If I didn't have those personal debt payments, that would be $2K per month in additional savings that I could put towards REI. It doesn't take that long to save up down payments if you can save $2K every month.
It would also help if I didn't have to pay out $200 every week for my son's daycare...but Dave can't help me there. :)
That being said, I don't follow the Baby Steps exactly. I bought my house out of order and financed it over 30 years to give myself options. My debt payoff date is March 2017, but that is only with the help of my rental (my house is a duplex, that I'm adding another unit on).
For personal finances, you should have an emergency fund set aside. For REI, you should have retained earnings, or Cap EX, or maintenance, or whatever you want to call it. Having debt without savings wouldn't be a good plan.
