How does the credit card cash advance roundup work?

[Brett Tousley]

I know there are several companies out there offering unsecured financing via credit cards.  Has anybody been through the process?  Would you do it again? What's the down low on the whole deal?

I'm curious to know why people are paying large fees to apply for several credit cards to access cash advances which are spendy.  Is it difficult to find these 0% deals online on your own?
