Hi John, considering that people have pretty much unanimously stated that they would be more thank ok with the two stage setpoing, for big Kanthal coils, basically, do you think it could be added? DNA 75/200/250 have plenty of power (according to the coil you can reasonably think of using) to have a preheat programmed, as it happens on DNA75C.
Please, do not abandon your first clients. The product is working still fine, don't force us to upgrade for the sake of it. Thanks.
