My comment is not about who's selling, or what they're selling. Check it carefully. It's about who's buying.
None of the sellers you mentioned were scammers. I didn't intend to imply so. My apologies if that's how it was interpreted.
On the other hand, people who bought the kits thinking that they were going to save money because they were kits, were scamming themselves. True kit-bulders, and there were indeed many, many of them back in the day, knew better than that.
