I have multiple airbrushes ranging from a $10 single action I bought 30 years ago to a nice Paasche H single action that is very nice.
The one I use most commonly is the $10 one as it's the easiest to clean the work I do is rarely that exacting/detail oriented.
Airbrushing is skill you develop with practice. Nothing wrong with starting out at the low end of the price spectrum to get your feet wet. If you decide you want to go further with it, you can always upgrade your equipment.
I occasionally look at the Iwata airbrushes at the LHS but can't really justify the purchase...too many reloads I still haven't tried.
