First, let me say, it's a good map, and it's well scanned and presented. However, it's the same exact map that's in the book "Titan." If you own Titan, you have this map. There's nothing new here per se; no additional information, no new names, no extra detail. Charging $3.00 for the same exact thing you already own seems...a bit steep, I guess.
Now, if you DON'T own Titan, I can see this might be a useful way to see the world, but frankly, I think you'd be MUCH better off buying Titan -- you get the map, AND you get the background information that allows you to effectively run AFF in the world it was set in in the game books; all in all, a much better deal and a much more efficient use of your money.
Anyway, that's why I gave it an overall "3" -- it's a "nice to have," I guess, but for $3.00, not so much. I'd strongly recommend you commit that $3.00 towards the purchase price of the AFF Book Titan instead; you won't regret it.
