I ordered a custom cue this year. I sketched a design and sent it to the cue maker last January, specifying the wood, joint type, joint collar length and material, what materials I wanted in the inlays, what weight, I wanted the cue. Basically I specified every detail of the cue.
To get all the above done took about a month of back and forth. Then I was told approximately nine months to build the cue and 20 percent down to get it started.
A several months later, the inlay work was about to start, I was sent cad modeled pic's to verify the inlays being done, I had a few corrections to make about a week later, I received more cad pic's which were correct and the cue continued.
A couple of month later received pic's of a cue with 90 percent of the inlay work done. That got me excited to see the progress of the cue. It is looking like my sketch.
Two weeks ago got a call saying inlay work is complete, ring work on shafts done. I have a problem with the weight because of the materials being used the cue will finish 1/2 ounce to 1 ounce over specified weight. Will that be ok. I was fine with that so the cue will be 19.5 oz instead of 18.5 not a deal breaker. Will send pic's next week, really excited to see the progress, but never got those pic's. I was a little bummed about that oh well.
From the time I paid the 20 percent nine months would be Nov., so cue is coming along fine. All the interactions above conversations, texts, pic's., e-mail were all initiated by the cue maker.
My personal experience with him has been positive.
OP sound like you answered your on question. Depends. If you want something unique or custom to you, then yes a reputable cue maker is the way to go. If you are happy with what you have, then no.
Hope this helps.
