I don't think selling second hand cars has done the new car industry much harm.
If only we were as big as the automobile industry!
I appreciate the comments and requests here, however we still prefer to respect the developers for Hauptwerk and ask that any second hand instruments be sold outside the forum. We have no issue with transferring licenses (and do it often), but this isn't the place to do so that we can better support direct sales which help the Hauptwerk developer community keep going.
Thanks for your understanding!
