Anyone used http://www.transitbangkok.com before?

It's an online guide to public transport in Bangkok. It's kind of handy.

Has all the Skytrain, MRT, public bus and river ferry routes and schedules in one place.

Plus, it has a basic trip planner running off Google Maps. You enter your "from" address and "to" destination and it maps out all the train/bus/ferry connections you need to get there.
