I will second John here. I have also signed up with CI for pretty much the same reasons (cheaper + EY). Rudi Hoffman is a fantastic insurance salesman and a pleasure to work with.
From what I heard from an Alcor representative: you essentially get a bit more security from them, than you would from CI. (Ben Best didn't seem to disagree.) CI is really committed to keeping the costs down, but from their presentation I gathered that they don't really cut the important corners, so they seem like a very good choice.
Rudi Hoffman is ... a pleasure to work with.
YMMV. I found him so unpleasant that I used a different insurance guy rather than continue interacting with him.
I’m hoping to sign up for cryonics when I can afford it, and I’m not sure which agency and treatment plan to get.
As of this Cryonics institute document, whole-body suspension with Alcor costs $200,000. Neurosuspension costs $80,000. With the cheaper but possibly lower quality Cryonics Institute, whole-body suspension costs $28,000 and they don’t do neurosuspension. American Cryonics Society is in between, costing $155,000 (again, no neurosuspension option).
What are the upsides and downsides of these options, in the eyes of people who are signed up, considering signing up, or know a lot about the subject? Also, I know there are some people here who have looked at cryonics and found it a bad decision. Input from them is also welcome.
