http://www.maxwell.com/ultracapacito...l/bcap0120.asp These are the Maxwell ultra caps that I would use... 120F, 2.5V each (You will want +20% pack voltage handling), and are ~$15 each.

Yes, Artur said the same thing, but I see that some companies are using Capxx capacitors and they have higher esr then the ones I looked at. I can get the ultra caps fairly cheap, but I want to see what these other high capacity caps can do and they are much cheaper and comes in higher voltage.

Edit: I have also spoken with a company that makes a hybrid, low esr, high voltage and high capacity cap, but the price on those are up there.
