I made my 2wg cables yesterday with a economical crimper I bought last year on amazon thats worked well for me for a couple projects now. I used this one. it provides a solid crimp with the terminals I used.

On the flip side I found trying to use this crimper to crimp the wrong size terminal ends to the wrong size cable doesnt work well... YMMV
