Source for tiny heatsinks for Pololu drivers?

Does anyone have a handy source for heat sinks small enough to fit on the Pololu boards? Digikey and Mouser don't seem to carry anything that small, and I'd like to see about getting a few spares to keep on hand for my 'backup' driver boards.

See this thread. Amazon and Newegg have them. They work pretty good, I think ideally I would attach all 4 drivers to a big copper CPU heatsink with a fan. That may be harder to work with though.

With that to put me on the right track, http://www.amazon.com/Cosmos-Aluminum-C ... 007XACV8O/ also appear to be the right size. Unfortunately I only found these after ordering the more expensive Enzotech ones! Oops.

I superglued small chunks of aluminum to the polulu chips, then used heatsinks that would have been slightly too large. It has been working fine so far.

Here you can find more than one type of cooler.

I carry the shorter aluminum version.
