It isn't the least costly choice, a Cryonics Institute whole body
cryopreservation is. http://www.cryonics.org

However neuropreservation does enable the brain to receive the best possible
cryoprotection, whereas preserving the whole body requires some compromise.
Also, vitrification of the brain is claimed by Alcor to be achievable,
whereas they cannot as yet apply their process to the whole body.

CI do not at present offer any vitrification, but their cryobiologist is
working on it. As with any competing organisations, there will be times when
one or other is "in front" of technological advance. My advice to everyone
considering signing for cryopreservation is to read as much as you can, read
all the cryonics service providers' web sites and then make your choice and
stick with it.

I also recommend the Yahoo Group "Considering Cryonics". Join it on
http://groups.yahoo.com/group/ConsideringCryonics
Look at the group's archives and you will find quite a bit about cloning
questions and answers.
