You only get a real fico score at myfico.com. It's the website of Fair Isaac, the actual fico people. It's what a bank will use when you try for a loan or mortgage. What you get from the various credit reporting agencies (equifax, transunion, experian) is commonly referred to as "faco" scores. They can be as much as 100 points different than Fair Isaac.
Also, they have a free deal where you get a equifax report and score.
EDIT: I just noticed that this is myfico.com.
