Hi guys, I stumbled upon the Yahoo Pipes technology a couple days ago and decided to use it to create a tool that searches all 130+ Craigslist sites in the USA for 300-series Diesels for sale, consolidates the listings, and sorts them by listing date (newest to oldest). You can access the results via the URL below, or by subscribing to the RSS feed.

I have filters set to exclude vehicles from 1986 or later, since I created this for my own early 80's purchasing wants. You can clone this pipe and edit the filters to your own standards.

In the coming days I will modify even more to include eBay listings as well, so this feed will eventually be a comprehensive search across several properties for 300d/tdt/cd/dt/sd's.

Hopefully this is helpful, if something like this already exists within the forum sorry for duplication :-)

Feel free to make suggestions, this is just my first crack at the utility. . . lots of room to improve filters, etc.
