If I am interested in a product and the seller doesn't
provide even the most basic specs or worse, list a product and not say if it is an amp, pre, speaker, etc then I will not buy from them. If the pictures show a lot of dust (are you that lazy that you can't even bother to make the piece you are selling look saleable?), stuff piled on top of it or no pictures and the seller refuses to send pictures then I won't buy from that person. If the seller or buyer doesn't have any feedback then again, I won't do business with that person unless I am selling the item and I get paid via Paypal first.
Lately, there seems to be a lot of jerks selling and buying in the classifieds. And yes, I look at the ads every day and even if I am not looking to buy something, if something catches my eye I may buy the item provided my minimum criteria has been met.
There seems to be a lot of arrogance here as of late and IMHO our hobby can do without it. I always list the minimum specs, take nice pictures, the item looks clean, and I always make a sale within the first week. As a matter of fact, I have listed stuff I thought would never, ever sell but amazingly it does and I am sure it is because the ads look good and the price is right.
There was a guy selling an Audible Illusions Modulus 3A preamp here a couple of months ago and he had the list price of 3,895.00!!! I politely sent him a message saying that price was for the much newer Modulus3B and that the 3A sold for at least a grand less and he told me to go f#%$k myself. So much for honest sellers.
