who?
Mouser is an electronic webstore, and you should try to hit it if you want a semi large quantity of switchs right now. 7bit has a thread open about the last group buy in the group buy section, and a poll in the poll section for the next GB. Or you can PM him, if you want more details.
You can also go on the Octopart site and type in the switch reference. He'll get you a list of seller.
