Hey Al,
I actually work in the finance industry and can give you some feedback. I can tell you this:
1) avg. time to get your money back is 5-6 weeks, but could be longer. There is an actual claim process, typicaly the reps are overloaded with calls, etc. so expect to be patient.
2) FDIC only covers interest on CD's up until the day the original bank is taken over. So as an example Integrity Bank in Georgia just failed and the branchs will open as regions bank on Tuesday.
3) The process can vary as to how quickly you get your funds back based on the means by which the FDIC takes over the bank and the transition to the new bank.
So in summary, You might want to weigh the difference in interest rate vs. possiblity of bank failure. If the bank fails your original rate of return goes out the window as a percentage of the time you will not be earning interest on your money.
I have been thrust into dealing with about 3 of the 10 bank failures, none of my own doing. IMO thus far the FDIC really has handled things very well. Like I said Indy Mac bank was about 5-6 weeks before most assets were distributed to the FDIC limits. Given the size and number of customers I think that is fanastic work.
