Data to determine what to charge for rent

[Jeff Howard]

What are you using to determine what to charge for rent, I know this is constantly changing.  We were looking at a house to pick up and were very hot for it.  Zillow was saying rents were $1345-1375 in the area (looking at comparable rent listings), rentzament $1300  so we went to see it.  Called my banker (who rents houses) he said his friend who runs a lot of properties said $1125.  We went to rentometer and saw $1300, pulled comps on craigslist listings and estimated it at $1150.  

What is the best and fastest way to do this, is there a tool that sucks craigslist listings in to an excel file?

Trying to figure a way to analyze quickly, i need data.
