Just over two years ago I bought a KINDLE from amazon.com. I'm Canadian and at that time the Kindle wasn't available in Canada, so it came as an international order shipped up to Canada. One of the features of the Kindle that I like is the large number of ebooks that are in the public domain already and amazon will send it to your Kindle as a free ebook.
Over time I've become proficient at using amazon's search function to find free ebooks and then down load them. One of my recent finds was Tony and Maureen Wheeler's....Äcross Asia on the Cheap", and is free.
This was written two years before their first edition of South-East asia on a Shoestring.
The guide lists the route as starting in Darwin Australia to Bali, southeast Asia onto Istanbul. As well as Chapter's on Money and Food, there's also a Chapter just called 'Dope'.
