My yards will take pretty much any junky insulated wire for .85/#. Mine consists mainly of O2 sensor harness (thin wire with lots of plugs/junk) and battery leads and heavier wire from starters and alternators (heavier wire, but still with some junk). It's a mix, but I will cut off any steel brackets, battery terminals or other really heavy junk. For the type of insulated wire I usually have, I'm happy with .85. My yard guys always treat me fair on everything, and both of my yards sell me a good mix of automotive core material. That's why they get my business.
