Looking for mid range school again! (Bangkok)

Hi everyone,

indeed i asked this some time back but with not so much luck. Right now we live in the lower numbered Sukhumvit Soi's between Asok and Nana, and around here we seem to have two choices, poorly run free government schools and hugely overpriced International schools. When we lived in Phuket some years back there was a very nice selection of mid of the range schools at around 15, Protected content baht per term. My question is, are there any such schools in this region or nearby regions of Bangkok?

Many thanks in advance.

Dave
