According to the Thailand FAQ you only need a bachelor's degree to teach in Thailand, so if you can't afford a CELTA or CertTESOL I'd skip getting another cert. Unless that quid's burning a hole in your pocket. Those online certs are worth about as much as the paper they're printed on.
CELTA courses use this book by Jeremy Harmer and this one by Jim Scrivener as introductory textbooks to TEFL. They will teach you more about teaching than the course you linked at a fraction of the cost.
You could try posting this to r/TEFL as well. If you're going for a qualification then CELTA is your best bet and there's a CELTA trainee book that might be useful. Some schools also recommend Learning Teaching by Jim Scrivener.
Personally, I've never had the chance to take a CELTA course, but I have heard many good things about it. I haven't heard of the other programs you mentioned.
BTW, If you would like to pick up some general TEFL tips in advance of taking a course, I'd recommend investing in a comprehensive text like Learning Teaching.

There's a fair amount of information in the text on lesson planning as well as teaching listening, reading, writing and speaking.
Cheers.
