That is pretty amazing. I have three sets without the machine that I picked up over the years, one actually works. I'll be needing them though for my other I,Robot project that I never get to. Glad I don't have to look for one. Yikes! Bill Burger had one half of the set on ebay, it only went for $40 something. I won't bid on his stuff though so unfortunately didn't bother. That was not a bad deal though for a parts board at the least.
