It would be fantastic, if there would be a way to get this project going. I have searched high and low for good DIY alternatives, but none of the solutions and sound samples sound really convincing. And then some working units are not really user friendly - you have to tweak and re-tweak each time you change some of the settings, etc. The Paradox TZF does the zero flange perfectly and you can dial it in in many ways AND it seems to be simple to use from a user perspective, but the price of used units is off limits.
