I have the sister airbrush to the 360, the 155... and it is a GREAT brush! I say yes.. it would be a good replacement. Good fine line capability, VERY easy to clean... relatively trouble free!
The 360 adds the ability to use it as a gravity fed brush with its' small color cup that can be rotated around to the top. Although it does not hold much paint, it is perfect for detail painting when you need to get very small detail or in close to the model. It allows you to crank the pressure down...
good luck! I think you will be quite happy with it!
