Honestly, you share a system, a few detailed pics and get people jumping on your case because of choices over privacy, trying to knock your system by comparing it to Ionics etc etc.
It's no wonder that (concept 2o or Ionics for that matter) don't come on here.
Why don't you call them up yourselves if you are that interested i'm sure they will give you a similar costing and share the information (& correct components) you want to know.
