It's not so much the idea of the $1 opening bid being too steep for a parts set. Just the idea that there is obviously something fishy here... Wasn't this set already on eBay before? Somebody bailed on that one.
I thought (briefly) about bidding on it, but a 6+ hour round-trip drive just to turn up something with missing parts ain't something I'd be thrilled with, even for $.50.
If it's a parts set, just say so and start the bids at $1.
When I was an eBay newbie, I bought a 19" porthole locally. I thought I'd heard that the last-generation of porthole sets didn't use a separate chassis. The set came from a collector who knew better... Pretty sure he took the other chassis. Funny how that never came up in his ad. Now I have a huge doorstop in the basement of my rental house that I'd feel bad throwing away.
Somewhere, there is an extra power chassis waiting to marry my doorstop.
