I know that some of you are actively or passively looking for All-Tracs and parts.  I've been using the Craigslist.org scanning site http://www.craigzoom.com (also can use http://www.craigszoom.com) to quickly scan all Craigslist sites.  You can also choose individual states and then cities, all without having to change the URL.  

This is not the only meta-search like this. There are other sites that also search all Craigslist including a Google custom search, http://www.searchtheentirecraigslist.com, http://www.crazedlist.org, http://www.craiglook.com, etc.

In particular, the last site given http://www.craiglook.com has a nice web 2.0 interface, shows local listings based on your IP address, and shows images next to the listings.  This scanning site may soon become my favorite.

thanks a lot...very helpful!!

Thanks for the links.  Craiglook is especially useful - really powerful search engine with a simple interface.  

I like to use searchtempest.com
It allows you to search anywhere and gives you quite a few options. And it's quick to go through the different cities if you change the options to one city at a time. This is especially true when looking for something very specific.

sad to report that craiglook is no more - craigslist threatened legal action earlier this year, so they had to revise their format. now they only search oodle instead of CL  

i am happy to report that searchtempest works pretty well as a substitute, tho
