Craigslist is a vast sea of treasures, but it's one that's kinda frustrating to navigate. When I'm really ready to dig in, I'll just search for something and open like 50 new tabs with anything that catches my eye. But for more leisurely second-hand shopping, Lifelike Craig looks great. It arranges Craigslist results in newspaper-style columns, allowing you to save favorite searches, view results on a map, and post your own ads. Ugh. I'm gonna have like 24 mid-century dining chairs before the day's over. [iTunes]
