Asia - Getting from Airport to City In BKK??

What is the best way?

What is the cheapest way as i have to go in and out of the city 4 times in a week. Are taxi's the best way? How much should i pay to avoid getting ripped off?

I'm confused. This subject has been covered multiple times recently. Please refer to the search button. The correct answer is BTW-Taxi (Metered) 250-300 baht with tolls & fee fm Don Muang. 50 baht less to airport.

The cheapest is 5 baht by train. Less than 20 baht by local bus to Mo Chit.
