You would have to spend a lot of time navigating the moors in the dark to get from the point of getting vinyl out of the grave to "Puttin' on the Ritz".
There's no doubt vinyl can sound great, but I don't see any scenario where it's the primary medium for music as it was up until the mid-80's. Yes, I know, all the cool kids are doing it - but I don't think they're taking any shortcuts in the manufacturing. I think we have one or two guys here with a bonafide lathe. I'd rather co-op with someone with the real McCoy (that knows how to use it) rather than re-invent the process.
The particular tool/toy you reference, seems aimed at the DJ market, as are the rest of the Vestax products. A good LP would far exceed the 12.5kHz specification, but not many other meaningful specs listed. The gadget in question looks like fun, but knowing your passion for audio fidelity, I think it's a shortcut I would avoid if in your shoes. Sides are limited to 15 minutes. $10 blank, $500 replacement stylus every 20 hours. One-offs would be expensive. Short-runs would be just as cost-prohibitive. It may be fun, but it doesn't look practical to me from a business POV.
