All machines are equally simple, the problem with time machines are opposite, they are too complex. It was a good thought to make a fully adjustable tattoo machine, but that became the machines fundimental flaw because they never stay in tune for very long.
Also, im going to have to disagree and say the price point is cheap considering the extra CNC time that would go into making one, however its not worth it based off their preformance. So yea, in a way they arnt worth crap. Unless you get lucky maybe..
To legion666, if you are going to swap them, i would suggest you did the opposite.. the invaders are definatly better shaders, they are pretty awesome color packers straight out of the box.. Just my opinion tho, definatly a better choice if you do alot of color work.
I think danny could make badass machines if he would just CNC a onepiece steel/iron frames
