How do you feel about egg donation?

I literally can't make up my mind about it! Sometimes it's something I would consider - the payment is phenomenal and obviously the fact I could help a women conceive would be great too. 
I'm just not sure about the ethics of it, it some respect I kind of just wouldn't look at the situation of that egg being my child, it's the child of the women I gave the egg too but then I understand the reality of it that, it is indeed my child! What do you think about it?
