ING Direct, savings account. Interest rate in bank savings .2%, ING Direct interest rate 4.3%. You open one and put in $250, I get 10 bucks for referring you, you get 25 bucks for being so cool.
The only drawback, it takes 3 days to get money from your bank checking account to your ING savings account or vice versa.
So if you want a referral, holler. Or leave a comment.
