Shopping on Craigslist can yield bargains, but here are two tools I discovered via Lifehacker to help with your search.

Rather than click through each individual listing that shows up in your search, use Craiggers to quickly navigate. The site displays your results in the same window, so you can quickly click down the list until you find a viable option.

Lifehacker also recommends HeyCraig, a site that lets you set up email alerts for searches in your city.

Don't forget if you use an RSS reader you can also create RSS feeds for your Craigslist searches -- very useful if you'ree searching for something specific that you don't need right away.
