Your information is very out of date (10 years or so). As far as I can tell fastlane = ezpass for all intents and purposes. There may be a small difference in the initial deposit, and I can't comment on the relative customer service (although fastlane hasn't been too bad for a big bureaucracy), but there is no monthly fee and they all work anywhere you go. I can't imagine driving to/around NYC without one.
