searchtempest.com is a great tool for locating bingo pinballs on Craigslist. It's basically a front-end replacement for CL's clunky interface, but its real power is allowing you to specify a distance from your zip code that you want to search. searchtempest will locate and search all CL boards within the specified distance. I've searched most of the USA in a single operation by setting the distance field to 3,000 miles. If you haven't tried this tool before, it's worth checking out. If you have a different favorite tool for searching CL, please post it.
