Most Current Bangkok Road Map?

In your opinion what (which) is the most up-to-date Bangkok paper road map?

In my experience the "date" on the road map is in many cases misleading when it comes to the overall coverage. For example, some maps will show the MILLENNIUM HILTON on their map but will not reflect years earlier road changes...e.g..Surasak between Praya and Surawong. In particular, Nelles Map ISBN 978-86574--004-5 seems skitso.

OK. Which road map to you prefer?

Me....I usually rely on a GPS (Garmin StreetPilot) or a Thai friend for navigation. But, I am curious about what you think is the best road map.

Thanks for your thoughts.

PS Even foot paths fall short on some maps.
