Radio shack or one of the other electronics houses carry a variable regulator that can be put together for under $2.00.  It uses an LM-317 IC.  You can put it on a small piece of vector board with two or three other parts and you can dial up the output voltage you want out.  Build time less then 1/2 hour.
