CraigsList is a great place to find bargains of all kinds. Mostly motorcycles in my case. However, searching on one list after another is really tedious and kills a lot of time.
Enter SearchTempest ( http://www.searchtempest.com/ ). With ST you can specify a zip code and a radius and it will search all of the CL lists within that area. 250 miles from me takes in everything from Maine to New Jersey.
Better still you can specify wild cards so that xr6* will include both the XR600 and XR650. Maybe you could do it with CL but I never figured out how.
ST will also search EBay for you and return a list of matches.
A great time saver if you are a CL junkie!
