Kink vs Coyote v3

I moved a while ago and had to get rid of my estim gear as part of the move. I'm finally in a position where I can buy it back again but I was debating if I should go with the coyote or the kink box. I had the coyote before and it was great, but the four channels of the kink box is appealing. How does the kink box compare these days? I know back when it came out its lack of features, especially audio, was a major turn off but thats not really a deal breaker. My main concern is its build quality, likelihood of having issues that end up shocking the shit out of me unintentionally, how strong it is overall, and the quality of the stim when using it. I mainly stick to the basic programmed options anyways, so features like audio aren't a big loss for me.

Are there also any interesting toys I can get with it? I'm definitely getting some new loops and a plug, maybe another moaner or something similar, but anything interesting that would provide a unique or different experience?
