there is not a whole lot you can damage severely on an airbrush to begin with unless you chunk it up side a brick wall a couple of time, and run over it with lawnmower or something. the tip and needle are the 2 main parts that will ever have to be changed most of the time, and if you handle the airbrush with care, and be gentle when inserting and extracting the needle, they will last a very, very long time. plus, there is no need to remove said parts very often, only for a major breakdown and cleaning session, which is done about 2 times a year or so..........atleast thats what i've come to do. as long as you spray the appropriate cleaning solvent through each painting session, you'll be fine.
with that said, if you have the money to purchase the badger anthem you speak of, i'd say skip wasting the 15 bucks on the cheapo and get on with some real airbrushing. you might as well buy the airbrush that you really want and get used to using it instead of purchasing one thats more than likely not gonna last long and probably scare you away from airbrushing becuase of the bad experiences/perfomance of using a cheapo airbrush. bite the bullet friend, and do yourself a favor, avoid plastic airbrushes like the plague and pursue the badger brush that you really want!! don't be afraid of it friend, there is absolutely nothing to worry about. get the airbrush, thin a little paint, pour it into the proper container that hooks to the airbrush and pull back/press down the trigger and let the lessons begin. happy airbrushing friend. later.
