I'm probably the only one particularly pushing CELTA here, and I have never had any connection since doing the old CTEFLA myself 15 years ago. In fact, I was a trainer and head trainer for two years on a competing course that looked like it could be a serious competitor in its day, and I think myself and my team did a pretty good job. As I have written elsewhere, looking back I still think my trainees didn't get value for money, as for just a little more they could have got a certificate with much better name recognition. I also think having a clear message online helps battle the truly dodgy courses, of which there are many. If some well-meaning upstarts such as we were find it more difficult to break into the market, I have come to the (less than confident) conclusion that it is worth it to give a clear message to people who are thinking of "doing the TEFL" that there is no such thing. There's more on my mixed feelings on the matter here:http://www.tefl.net/alexcase/tefl/celta-love-and-hate/
As for Trinity, I think we could even be accused of bigging it up too much on our recent FAQ pages (http://www.tefl.net/tefl-courses/faq-te ... cation.htm
). As far as the OP is concerned it is completely irrelevant, as there is only one course in Asia and it is a part-time one (I think) in Japan. For that reason, I also doubt it has much name recognition in Thailand outside any British-owned schools that there may be. Also, 1600 dollars is exactly what the CELTA costs in Thailand (and many of the competitors are no cheaper). For 2400 dollars you get full board accommodation for the four weeks as well.
I've also never had any connection to IH or ECC, btw.
