Anything not production is custom, weither a custom is worth the $$$ is dependent on the level of craftsmanship, the design, quality, etc...
A custom zeepk is still a zeepk, but if the "custom" ones shave well, they might be worth $75?(I doubt it)

With any New razor, the more you pay for it, the more you are going to nit pick the details.
If I pay $1000 for a Zowada, I will be expecting a flawless razor, If I pay $300 for a Chandler, I will expect a good looking great shaving razor, with minor anomalies that will not affect the function or appearance of the razor. (No offense Joe) If Joe produces a flawless razor, for $300, Great for me, but at that price range, I'm not going to examine the work under a microscope.
I would still expect higher quality from these custom razors than a $200 TI or Dovo.

You also have to consider what you are ordering into the equation. The fit and finish of the razor is only part of the production cost.
Zowada razors are worth the price because he does all of the manufacturing himself. If I was able to get a Damascus razor blank, and just polish and hone it, It may look comparable to a Zowada(yeah right) but I didn't put the work into it that Tim does.
In other words it is worth paying more if you know the work really was done by a master, rather than a machined factory blank.
To me it's worth paying $$ for a Williams because i know he's at home pounding out my razor by hand.

The final word on value is not so easy, because it's whatever people are willing to spend... If I start making customs, and charging $10,000... It will not be long before my prices drop to a level that the market will support.
Each maker charges what the market deems his razors are worth. as soon as they breach that level, their sales will drop, and they will adjust prices, or spend more time on each razor, to bring quality and the market value of their razors up..
I don't think most of the makers make what they should for the time involved. Be greatful they don't charge by the hour like plumbers do...
