apartment hunting

As a side effect of our evil plan to repopulate SF with midwesterners(its already well underway - see where your co-workers are from!), we've found ourselves constantly cross-referencing craigslist and Google maps to plot out apartment tours. The huge frustration, however, lies in Craigslist's current inability to field multiple locations to a single map, to compare proximity and lay out a set of tours. This might be a result of Google's current capabilities as well, without a quick and easy way to set up multiple searches and persist the results? I'm not pointing fingers, but merely asking if we could all get along...maybe get a place together...spend some quality ti...oh, wow, that got weird ;)
