PadMapper.com

This is an AWESOME website to help you find your next apartment (to rent).
You browse with a map — so you pick exactly what area you want to live. no more mapping every damn place on craigslist to find out its in the boonies. Also, you can set up your price range, bedroom number and all kinds of criteria.
This compiles rentals from ALL Sites:

craiglists, real estate rental listings, etc.
My BF and I found a great place using this tool — I am forever grateful!
From their website:
«PadMapper is a web application by TopHat Monkey Software that makes it easy to browse through and pick out apartment and house rental listings that you want to follow up on. Instead of having a big list and then using a map as a helper for the list, like most of the real estate sites, I threw out the list and gave the map as much room as possible.»
