I have never owned one of his cues. However, I hear they are fabulous, play great and precision execution. However, in manufacturing, you have cost of materials, direct labor, overhead, and profit. Making for yourself, direct labor and profit can be blurred.
However, a cue maker should have a general idea what your price should be. Secondary market sales should have no influence on prices previously committed. Three friends made deals and the price went up on completion. Significantly!
Someone had to say it.
