I've heard a lot of bad feedback from many agencies in Bangkok but not any good feedback.

I would like to contact a good agency just to check what they can offer me. Can anybody recomend any? Thanks

I've worked for Siam Computer (Victory Monument branch)for the past 6-7 years. I've had no issues with them. All teaching materials are supplied and there's back-up should it be needed. The most important thing is that your salary is NEVER late. They are a very big agency, so of course it's possible that there might be teachers that don't agree with me, but I'm just talking about my experience with them so far.

I should finish by saying, I work for the main office. Siam Computer has many smaller branches around Bangkok that might not be as well organised as my branch.
