home depot sells a spring kit [www.homedepot.com]

that contains several kinds of springs. i also has some that are 1/10inch diameter wrapped into a 1/2 inch diameter coil. very strong compression strength.

I like rubber/silicone washers instead of springs.

Inspired by Greg I also use a couple of layers of silicone washers made from a heat mat (like this: [www.thingiverse.com] ) on my gregstruder. I've used it for almost a year now, and it works beautifully. The tension is very high, but they have more give and caters for uneven filament way better than when I used a spring.
