Washington Mutual currently has a 5.00% APY rate on their 6 month online CDs, and a 4.50% APY rate on 5 year CDs. While this is a somewhat competitive rate, WaMu also has a great deal on their 5.00% APY savings account that would allow you to get a high return on your CD while maintaining a degree of liquidity.

Minimum balance on all CDs is $1,000, and are only available online. Opening in person will yield lower rates.
