Cord blood

I am comparing between 2 different private cord blood banks in Singapore, Cordlife and Stemcord. I am fully aware of the benefits cord blood can bring as currently it is said to be able to treat 72 diseases and as technology advances further the figures will surely increase. Keeping my baby's cord blood has always been a form of consideration for me and the charges are relatively affordable. I knew someone working for Stemcord and he has also promised to give me some promotions if I intend to keep my baby's cord blood with them.

There is a free of charge way to keep your baby's cord blood and that is through public cord blood bank, but then you will have no ownership of your baby's cord blood and it will be treated as samples for lab testings. Therefore I feel that I should keep my baby's precious cord blood in a private blood bank.

Now I have only 2 choice to make... Cordlife or Stemcord? Has anyone kept your baby's cord blood with any of the above banks? I would like to seek opinions from you.
