Hello looking into getting my ED visa as soon as possible any recommendations on good schools and about how long it takes to receive the visa?

As my last post just got polluted by non relevant comments, here I post it again hoping it won't happen again, thanks.

QUESTION ABOUT ED VISA AND PROPER THAI LANGUAGE SCHOOLS IN BANGKOK.

I'm thinking of taking Thai language classes in Bangkok and I'm wondering about price/quality/smooth visa process from different schools in Bangkok. Anyone could recommend a proper very good school for someone who really wants to attend to the classes ? What about the price ? And how long is an ED visa valid now ? If I'm not wrong it was changed from 1 year visa to 9 months now, not sure about that. Also, is the process getting more strict to get an ED visa due to the recent police raids in schools in the country ? Thanks in advance for all your recommandations.
