Help Request: Cryonics Policies

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.
