Don't know if I have seen the one you are referring to Jim, but from the description it sounds like a nibbler. They have been around for years, like a lot of paid advertising they certainly can do what they show if you have the skill. Trouble is most don't have the skill or the inclination to put in the hours need on the tool to develop it.
Started another sideline today, have been casting bullets for years and today I decided to list some on one of the free to list firearms websites.
Had 2 enquiries about my 370gr .459 coated HP in the first 4 hours. Wasn't sure how to price them so went with alloy cost + a nice hourly rate to cover the time to cast, coat & size. Only trouble is only had one box left after loading for myself the other week and have orders already for 4 boxes.
Will have to have another big casting session just had another call while I was typing asking for another 2 boxes when I can get them done.
Plenty of commercial bullet casters in Aus but no one I know of doing HP and hardball seems to be standard across the board. I guess automated casters don't lend themselves to HP. I'm casting these from 2:2:96 and surprising the number you can cast quickly with a 4 cavity mould. I usually run 2 or 3 different moulds at the same time to really speed things up pouring one while the others are cooling.
