I did a parametric search on TI and found this: http://focus.ti.com/docs/prod/folders/print/opa251.html

The opa251 is single supply, can handle 36v, and has rail to rail output. (meaning that the output should go to the same voltages as the supply.) Apparently you can get free samples of this chip from TI. If you are worried about overvolting it you can always use a resistor and a zener diode to protect it.
