when i started i bought a chinese ab where the retailer had branded with his name , when i asked the owner what was the diference between his brand and for example paasche he yelled at me that all airbrushes where the same and that paasche,aztek and all other brands where a bunch of robbers, so i bought it.long story short i finished buying a paasche talon(cheaper than his socalled brand) by the internet and yelling the guy that he could stick his brand of chinese abs through his...i expended twice the money for nothing.because the chinese here was more expensive than the talon.
well what you need is to have the best ab for what you want to do. for example i can do with a talon what an infinity can do, but the talon is not as consistent like the infinity.also other aspects like design, not how it looks which for me is "finished", im talking about the engineering invested in it,take for instance:balance,the infinity i can place it between my index finger and my thumb and it will stay put,while the talon wont.but as as working horse the talon for me is far better than the infinity.
i don´t think that the inifinity is over priced,neither the talon, the krome well i don´t know since i haven´t tried, the masters or other chinese, don´t, in the name of what you care the most, buy it.
in the end you are paying for some extra values,casing, presentation,reputation, but above all engineering
so to start you need something that is consistent,reliable at the right price for you.
