Searching for battery contact springs

I am looking for battery contact springs for my pen hosts. I am aware Odicforce (Contact springs for use with driver boards for battery connection, 5-Pack - Detailed item view - OdicForce Lasers Online Shop) sells them, but I am looking for something closer to my side of the pond.

I searched on digikey, but could not find anything small enough.

For those unfamiliar, I am looking for springs similar to those in jayrob's pen host kit.

Battery Contact Springs products, buy Battery Contact Springs products from alibaba.com

You may have to order 1000, but it only adds up to $10 or so. I'm sure other members may need some too.

Not quite what I was looking for, but thank you for the suggestion. There are many other options on alibaba, so I will keep searching.
