It's the same thing that has happened to the car hobby. Barret Jackson being the largest destroyer. Ebay is in there too.
People see these exhorninate prices (regardless if they sell or not) and think they have hit the mother load. I see people asking 5k for $800 cars or someone who did a "clone or tribute" vehicle and ask outragous prices. I see rusted out decroaded pieces of crap where the roof is the only good part on the whole vehicle and it's stripped too and people ask crazy money for those because of the "potential value".
I repair chainsaws occasionally too. Same story there. I'll try negotiating the purchase of a saw that say has been straight gassed and these people want darn near what a running saw goes for. See-ya.
I know how you feel.
