Where to buy new iMac mic?

After doing some switching of internal hardrives in my iMac I noticed the internal mic stopped working. I cracked it open again to see that one of the wires had come unsoldered. I've resoldered it since but for some reason every now and then it stops working. I figured I should just go ahead and buy a new microphone for my mac. I tried welovemacs.com but couldn't find anything that looked compatible.

Would you guys know of any place that would sell an intel 2006 iMac mic cable?

Ebay is a good place to start for parts.

There are several other partstailers out there. applecomponents.com is a small shop and you can email them a parts request - good folk to deal with. ifixit.com is a bit pricey, but they've got a lot parts. If you go with them use coupon code survey407 for 5% off.
