I am also on the lookout for high interest rate for money market accounts or CDs. This morning I came across two rates that were worth mentioning. 1) HSBC DIRECT. They have a 12-month CD that is paying 2%. While it might not seem that high, that is the highest rate I have seen in a long time to lock in for a relatively short time period.
2) SmartyPig. Take the name with a grain of salt. It is FDIC Insured and paying 2.75% for a money market. There doesn't seem to be any other catches for now. Let me know if you have an account there and your thoughts.
