Alternative to MLS

[John Yu]

What is the best alternative method to search for properties if you want to focus on MLS listings but without MLS access? Personally I found Redfin is the best alternative as new listings show up on Redfin as soon as they are on the market. Does everyone agree? I noticed Zillow and Trulia are usually a few days old. I don't understand Zillow being a public traded company can't get their listings updated or pulled from MLS as quickly as Redfin. Am I missing something?
