If you have not visited this website yet, you are definitely going to like it (http://www.stemcellresearch.org/index.html
This is an anti-embryonic stem cell organization. There Founding Statement recognizes the use of embryonic stem cells as unethical since the cells are inevitably destroyed. They have catalogued much of the debate (of course from the pro-alternative perspective), from 1999 to present, regarding the use of embryonic vs alternative stem cells. Additionally, at there website, you will find links to papers favorable to stem cell alternatives.
If you are interested, I would encourage you to read their Founding Statement and then take a look at the Facts and Information section.
