Speaker Cable suggestions

Hey,
I want to start making some speaker cables to compare. I am currently using some 12ga zip cord (Sound King) from my Levinson ML-9 amp to Vandy 1c speakers.

I want to try out other cables that I can get for under $10 per foot. Any suggestions as to what to try? I've only used the zip cord and in my prior setup with Vandy 2ci's I used Nordost super Flatline (not the easiest to terminate myself).

Thanks,
E
