@Homepin needs to stop replying to the trolls too. A lot of Aussies on Pinside seem to have it in for him big time and just openly trash the pin, him and his company. Hard to know how much of that is due to him "selling out to China", but it's pretty weird nonetheless. The Homepin/Thunderbirds threads on Pinside are pretty toxic and I'm surprised Pinside management let a lot of the stuff fly really, but hey ho.
Like it or loathe it the guy has developed, manufactured and sold a pinball machine - despite some serious adversities along the way from the sounds of it. That deserves a level of respect even if you don't like Thunderbirds at all.
