did you get a price for the CT? I found a place that will wind custom toroids 2 for $10 plus materials or something like that.

I need to find a way to do this cheap, as I want to monitor each device and it's current draw.
LIEBERT makes power strips that monitor total draw for the strip. The strips are ethernet enabled and use SNMP to report paarameters. They are kinda spendy $500+ I think.
