In my opinion a lot of these guys don't have a long list of people waiting for cues. They have sugar daddies.
Basically there is one guy that will order 5-10 cues and he immediately gets bumped to the very top. So over the course of a few years, however long these cue builders finish the order, will make for one guy.
5-10 cues isn't exactly easy to make so it will cause a waiting list. In the mean time this sugar daddy is receiving cues that are finished one by one. He sells it and claims there is a super long waiting list. No shit! You ordered 10 cues. So he sells them off or keeps them. It's an artificial market inflated by their sugar daddy.
Now the same can be done for dealers as well. Exclusive to dealers.
So when people say there is a waiting list. There isn't one. There may be one from their sugar daddy.
I know a big name maker and I have a suspicion they operate like this. This company has a guy that speaks on behalf of the company but can't help it but show off his latest cues from them, yet there is a supposed waiting list. His ego got in the way and he started dropping clues like how he helps design cues, how complicated his cues are etc...etc...
