I am still in the game and looking. I can not afford to go the ~$10,000 I did the first time around... Fortunately, most of the current parts are reuseable. I just have to source a larger heavier frame, and the ability to generate more force. Of course I will have to scale all of the intermediate jigs and fixtures... But that is mostly time.
I will continue looking as long as there is interest. Unfortunately, there is a bit of a catch 22 here... Most people want a price to determine interest, and I can not set a price without making a few to ensure I will not work myself into the poor house. In order to make them... I have to buy the machinery, and that purchase is based on whether I feel I can make my money back from the project.
Business administration stuff sucks
