For mine I went to Novena Fetal Assessment centre. Oscar about 300+ and Harmony at about 900+. I already thought its expensive until I saw your prices!
Yes rac_bow, I'm under Dr Steven Teo also. Recently just completed the embryo transfer and just waiting. I find him to be a serious kinda guy and looks competent. But there isn't any forum discussion on him though, so not sure also haha.. Hopefully good!
