With banks and money markets paying virtually nothing these days finding good places for short term cash is a bit tricky. Even most of the traditional high yield savings accounts have gone under 2%.  Currently GMAC Bank is offering 2.5%.  As of 2008, GMAC Bank is FDIC insured and has full access to treasury liquidity programs, so it is considered pretty secure these days. Even in the worst case, FDIC normally get money back to investors within a day or two of taking over.
