I bought one yesterday at 22.00 plus ship on eBay. The guy had 5 total NOS sealed. He still has a few so if you are looking for one there ya go. Are these rare? I don't recall ever having seen this kit. I love goofy stuff like Dave Deal and T Daniel so this is right up my alley. That and it is completely representative of the period. At 22.00 it's cheaper than a modern kit and the subject was [for me] hard to resist. Any built-ups around? Bob
