ING Direct's ShareBuilder is offering $75 if you open a new ShareBuilder account and make an initial deposit of at least $100 by 12/31/2011. Unlike previous ShareBuilder bonuses, this doesn't appear to require a trade (The $100 Black Friday bonus required 2 trades).
It's important to note that ShareBuilder is ING Direct's brokerage business and not the bank. However, ShareBuilder does have an FDIC Insured cash balance account
that can be used to hold money before or between trades. This can be chosen instead of the non-FDIC insured money market fund account.
This bonus is listed on ING Direct's front page and at this ShareBuilder page. Offer code is EXTRA75
