Can anyone recommend a good english-english dictionary available in Thailand?

I am more interested in the quality/accuracy of the definitions rather than the number of words.

Well, in theory all of the dictionaries are available, at least by special order from Kinokuniya (if not actually on the shelves). I don't have a favourite personal dictionary; of course the OED is pretty good. Were you asking what is available at Asia Books or the other chains that are more likely to be outside Bangkok?

Most "college" dictionaries are a good balance between detail and brevity- try Webster's.

I'm interested in something for a Thai (intermediate to high level English student) audience, and something available (preferably) inside or outside Bangkok. Something that English teachers might recommend for students.

You want a learner dictionary.

I'd recommend the Cobuild.

The Longmans Dictionary of Contemporary English comes with a CD ROM so you might want to try that.
