The best advice I can give anyone is to do it for yourself. If you're taking the EFL online courses JUST to get a teaching job, then by all means choose whatever one you want (cheapest and shortest sounds good), but if you're planning on using what you have learned, go with one that has a widely known reputation.

Get the Certificate for what it can teach you, and do it for yourself. Going into a classroom without knowing what you're doing rips off the school, and will only frustrate you in the long run. Not that someone couldn't pull it off, but I've never actually seen it happen. Most people I see stomping out of a classroom swearing at their students have no training and were only coming for a year anyway. They were more interested in getting to see China at the school's expense, and the demands of teaching eventually wear them down because they were not adequately prepared.
