Questions About Bulk Power Cable, Sugestions Needed

I am building a 40 foot power cable with Furutech Male ac and female IEC connectors. I want to get out as cheap as possible and so far have found the Cardas 10X3 Bulk Cable at around 16.29 per foot, but it is solid core. It is 10 gauge which I prefer but that means having to solder the wire to the Furutech connectors. Does anyone know of a cheaper alternative to this cable as 40 feet adds up to 600.00 alone in wire! I am looking for suggestions but not interested in Romex or other industrial type wire. I prefer something similar but stranded by another manufacturer, perhaps someone less known? Also not interested in silver wire and I prefer 10 gauge.

Can someone chime in?
