Some very good and important points lad's. It's alright walking into Lidl and reckoning you've got a bargain, but after a few months things can begin to give trouble. Look after your equipment clean your airbrushes regularly after every session, learn how to mix your paints to the correct consistency. If using enamels spray in a well ventilated location and wear a proper mask. They cost around 30 Euros and are essential. I've seen some imitation Zippo lighters in the past but they ain't Zippo's and do begin to fall apart after a while. It's the same with any precision tool buy the best you need or can afford. There are tonnes of spares, and online support available.
Needle files are a classic example I have a set Swiss made files and needle files the cheap pack of 8 for a fiver don't just cut it in the long run. I stopped using cheaper cutting knives and scalpels in the past and now I only use Swann Morton knives. It makes a difference in the long run. Putting aside all opinions practice, dedication, and studying the prototype are also as important. Acquire the skills and believe me anyone can do it with practice. If you make a mistake start again don't hope the next one will be better once you get the first one right you won't look back.
Rich,
