Yes I agree with cakebelly. Modelling chocolate is so forgiving and there are techniques you can use to make things ahead of time which can be a life saver on complex designs.
I have an ordinary air gun with compressor but I believe the one by Dawn Butler of Dinkydoodle designs is super quiet. She also has a range of airbrush colours which can be used on chocolate and fondant thus saving you money as you only have to buy one sort. I also mix them together to make my own colours. She has some demonstrations on you tube.
Hope this helps and good luck.
