I had an old 4211 sunflower disk chisel that was on it's way to the scrap yard. Listed it for $1,500 cash money. I thought I had it listed appropriately (just over scrap iron price and the tires held air) I had over 30 responses in one single day.  About 10 were scammers, 10 were tire kickers, 10 were serious.  The amount of responses was overwhelming.  Sold it to the first guy who would actually talk to me on the phone and he picked it up the next day.  Hard to say if I got back to all of them after it was sold but it definitely was a flurry of messages going back and forth.

I've bought and sold a few items.  It's kind of nice being able to somewhat see if the person is "real". You can sort of tell because you may have mutual friends and then you can ask about the person.  Example, I just bought a junker snowmobile for the boys to fix up this winter.  Turns out the guy was neighbors with the in laws.  Not really upstanding in the community.  Went to look at the junker and "ran when parked, only needs carb cleaned etc."  Got a bad feeling so negotiated knowing I would have more into it than he stated.  Sure enough, we ended up having into the sled what we pretty much anticipated.  Carbs were missing pieces, assembled incorrectly, out of sync, etc.  It may have ran when parked but certainly not very well!  Anyways, having being able to vet the personality before even showing up certainly helped my willingness to negotiate.
