Early days of ebay there were almost no pictures. Anything with a picture sold for more.
As pictures came on, there were 2 kinds, good and bad. Same result.
Next layer, dirty versus clean - two ways to look at that - dirty will probably be the deal, maybe even flip territory. Then there’s dirty/ bad pic, obscures reality, sometimes that’s tantalizing and brings higher bids. Dirty/ good pic...that never worked out.
My gear in the racks gets dusty. I don't think this is some sign of abuse.
Yeah, stuff at our shop gets shockingly dusty, considering it's a closed space with not a ton of foot traffic (esp this past year). My partner chalks it up to fiberglass fibers....considering I'm sitting around the joint all day breathing that stuff in, i hope he's wrong!
