I just love Ajax applications and here is another one from Bankaholic who has come up with certificate of deposit rate comparison engine which would let you compare interest rates and customer reviews of more than fifty national banks and credit unions.

You will be able to classify the table in terms of period, rate of interest, bank rating and minimum deposit but customer will also be able to add up their own ratings. The interface is pretty cool and user friendly. I hope it gets a good response from customers.
