I'm planning to go with ACS, which is a lesser known cryonics organization that has been around longer than Alcor and CI. The price for a full suspension is $155,000 which is in between the CI and Alcor prices.
They don't actually run their own facilities, instead they contract with other organizations, currently CI to hold the vitrified bodies. For doing suspensions, they seem to have their own procedure, and you can additionally choose to have them contract other organizations such as Suspended Animation Inc. (which is the one Alcor uses).
Since they contract, they have increased flexibility which seems quite valuable. In particular, it helps against organizational incompetence which both Alcor and CI seem to have their fair share of. It's harder to find info about the competence of ACS themselves, but the fact that they've been around a long time bodes slightly well.
They also sponsor cryonics research, which is really cool.
Anyway, I'd really appreciate having more people analyze them as a cryonics option before I commit to them!
