The only issue is what geocoding method you need. There are more than a half dozen which all work for areas in say Florida, but for locations in New York you end up with pointers to the opposite street corner. I forget what version we use here, but you want to be sure you are geocoding correctly, especially if the Government is over your sholder. The only issue I have with many of these site is they all use the same images that in many cases are 5+ years old.
