Really, how about a $25,000 Black Boar or any of the other top of the line custom cues? Many that start at $1000 and rocket up. I think people spend what they want to and what they have the means to spend.
Now your getting silly, how many pool players actually own a 25k$ cue? My bet is that most of the people that own the super cues don't even hit balls with them, they are in their collections.
Now I'll bite on your $1000 for a top notch custom. But the fact is when you pay for that cue its going to last past your lifetime, and possibly past your childrens lifetimes. Golf clubs wear out.......
You can buy the best pool table on the market, and have a 1k$ cue for the price of the best set of golf clubs on the market.
