Ok, so I found Alice on ebay Canada. Turns out to be $1.79 each when I buy 10.

I guess nothing stops me from adding a zener/crowbar/fuse setup in front to make me feel like I'm doing something.


I can even afford a one-way diode in case someone uses a wall-adapter with a negative center (I think all the ones I have are positive center).


I hope you get a freebie for making her a sale.
