I've found quite a few by using "search craigslist like a madman". You have to use Mozilla Firefox to get it to work. It can search every Craigslist site in the US.
I like to take my mouse arrow and move it to the far left side of the screen, push down the wheel, and then move the mouse slightly to the bottom and left to steadily scroll through the listings. You can hit the escape key (top left of your keyboard) if you see something that you want to read and it stops the scrolling. You can also push the wheel button again to stop the scrolling.
