I was typing a response to a post complaining about a cue maker taking too long to deliver a cue. The thread apparently got deleted before I could respond. (My response was "so what". I had a cue on order, put lots of cash down, the cue maker died, and there are more important things in life when someone is terminally ill. I lost a lot of cash on this deal, although I got a partial forearm since I had photos to prove it was my cue. It is not a perfect world. Not as much fun as spending your money on lap dances - but Oh well.)
I see a problem where someone offers to sell a cue but does not give a price. Everyone bids against each other, and the highest bid or bidder with less risk and better reputation gets the cue. You might say nobody is holding a gun to the Seller's head, so the seller should be able to decide what they want to do with their cue. Or somebody buys a cue only to sell it for more money in a short period of time rather than shoot with it and enjoy it.
I offer the forum a partial solution. Develop a detailed specification for what is a cue, whether it is straight (including varying degrees of straight), how to measure its length, how to determine its weight, the butt weight, each shafts weight, what different levels of use are, quality of finish, etc. Other than photos, most cue sales look the same. Develop specifications for defining these descriptions of a cue on the forum. There are two (2) levels of sales. (A) Risky {ebay style} and (B) ones where the cues are sent to the moderators of the forum for a fee as well as cash. If the buyer is completely satisfied after getting a cue after a period of time, the cash automatically goes to the seller. Sellers know this will happen, but also know someone actually has the cash before a cue goes to the buyer never to be seen again. Others do this, but it does not put some cash in the pockets of those running to forum to help with expenses. Plus, the moderators are generally ethical folks. They can even "moderate" if there are differences of opinion.
(Now back to your regularly scheduled program.)
