Based on my experience with the Talon, yes, it is a good airbrush, capable of doing very nice work.
I agree completely with Don Wheeler, buying used can come with some risks. Not all AB's are sufficiently maintained by the owner, if it comes to you with problems you might just end up replacing parts, that equate to your spending a total amount equal to the price of a new airbrush.
Chicago Airbrush, Coast and TCP are reputable authorized dealers, look for specials, they come along frequently. All of my purchases through them were entirely satisfactory.
Good luck with your search.
