NO/NC Momentary bypass - where and what to get?

[cajone5]

Who makes the best true bypass that will work with a momentary NO or NC switch?

I saw this... https://www.mammothelectronics.com/products/click-less-true-bypass-relay-module-kit
And it got me wondering who all makes these things and which are the best in your opinion?  I feel like $20 is a bit steep but I don't have the relay or IC that I can see in this photo on hand so I'd be sourcing quite a bit to build something similar.  Anyone use these switches a lot?  If so, what do you use and why?  I have a build I'd like to use it for in the near future so I can use something other than a normal stomp switch.

Thanks!
