If you are looking to park some of your money into fixed deposits, then you might be interested in Qotion. Instead of checking with all the banks individually on their interest rates, the site qotion.sg does it all for you and puts up the information for your comparison.
Qotion does not charge any fee for the service but you do need to register as a member to use their services. At this point in time, registration is free.
They also provide some comparison of credit card, credit lines and loans.
