I note a large 47uF ceramic cap is suggested....but then they add 0.1 ohm to increase the ESR.
As alum polymer caps have much lower esr than 0.1ohm, I am leaning toward using a Nichicon PM series 470uF alum electrolytic instead to have a similar ESR. http://nichicon-us.com/english/products/pdfs/e-pm.pdf
