Just for fun, I had a look at the most recent reglatory financials for Self Help. They are small ($100 something million in assets) and they appear to make fairly risky loans, since almost 5% of the loan book is delinquent. However, when loans do go bad, they are able to collect most of what they are owed, with a net charge off to assets ratio of less than 1/2%. To compensate for the riskiness of their loans, they have a lot of capital (22% of assets at 6/30).
Self Help looks reasonably safe. They probably are marginally riskier than someone like Pen Fed, but they appear to know their business and make a fair amount of money, considering they are a non-profit. Probably a reasonable place to put your money, assuming you get good rates and don't go over the deposit insurance limit.
