Hi,
Pens of color has them in stock according to their on line cart (wich is usually accurate).
They are $2.95 , 2.70 for 10 or more wich is probably a little cheaper than PSI direct and Sheila is a great person to deal with.
P.S. If you look at this site, you will realize that you don't need a kit to make tham, just what is called a crocodile clip from any electrical supplier (few cents each) tiny pieces of rubber hosing for aquarium and a blank.
