There is very little or nothing that is risk free that will pay much of course.
One thing I like to put money into to try and get a better return is CEFs (Closed End Funds). You can find alot about them at
www.cefconnect.com.
There are CEFs that invest mostly in bonds, some invest in stocks (and often do covered calls, etc.). There are differences of course among how risky of bonds they invest in, whether they just do Govt. bonds or Corporate bonds, domestic or foreign, etc.
Many of them pay dividends monthly which I like, and some pay quarterly. Also, they all have a NAV (Net Asset Value), which theoretically at least is the correct value of the fund, but since they actually trade during the day, they can trade above or below the NAV. When they are trading below the NAV, they are said to be at a "discount" - over the NAV, they are trading at a "premium".
Again, there is risk - view the 5 Yr charts when possible to see how much they went down around the Lehman collapse time. Most have recovered quite a bit since then, but if you needed your money during those times, they wouldn't have been so good be holding. So, these aren't money markets by any means, but they can be good income while you wait for whatever you wanted to do with your money.
Currently I'm long CSP and HYF.
