Do you remember the old days when Kittmaster spearheaded making a new version of this? I think they did end up with a finished version but you'd have to do a deep dive into the forum reader to find the info.
I tried looking up the threads, I think Kittmaster was even trying to get molds made but it was a silly money price. Just going by memory, maybe $300 back in 2008? Nowadays you can buy a controller board on Ali for 99 cents, wow the electronics world has changed.
