Honestly, I don't know. It depends on how usable the service is. I'm currently paying $36/yr for a vpn, $20/year for mail, and $12/year for password sync.
Ideally I'd like to spend about the same, and be able to move my file syncing away from Dropbox/google drive, and my calendar off google. I'd be willing to pay a little more to support a cause though.
