Why a couple months? Get a CD. You should have years to use the stock market. If you got only a year, try some TruPS. (Trust preferred)
I like "The Goldman Sachs Group Inc Pref Share A" (GSPRA) right now. (On a dip) Your principle is pretty safe, and you get a minimum coupon of 3.75, which gets you about 5.5% at the current price.
Unfortunately, my call on this is about 3 days late, so you might have to wait for a dip. If Goldman Sachs gets into financial trouble, you proably end up owning the stock; but if goldman gets in trouble, you would probably be better off buying a gun to protect the homeland from the invasion forces ;-) Does Goldman ever get in trouble?
