Looking for pure copper or Cu/Au bananas

Hello friends,

Trying to order a new set of DIY speaker cables. I have most of the connectors but need to order two pairs to replace bad Furutech bananas.

The requirements:

• Solid copper or gold over copper. Absolutely NO brass core.
• Screw down wire connections.  No soldering
• Either fully insulated or easy to insulate, so nothing with a metal housing.
• Less than $80

Suggestions?
