Help with NR-R-NR wire joining options.

[Rictic]

Can someone please post a link to the little silver wire joining clamps (crimps); I'm afraid I might google and purchase the wrong/less effective ones. I'm working with 32ga nickle NR and 32ga kanthal a1, in case that's relevant info in knowing which ones to buy. I've tried the zapper and several twisting methods with inconsistent and frustrating results. Most likely my fault, but I'd like to try my luck with the clampy things to see if that works better for me.
