No experience with that particular brand, I just have a general opinion on shopping for airbrushes.
ABs really are a precision instrument. Tolerances have to be slight for good function, otherwise you're fighting more than painting.
I have two Iwatas, one 30 and one 2 year old and the design is exactly the same, the only change over time is the box from wood to plastic. The 30 year old performs as good as it did on day one, I only got the second so I have a small chamber gravity feed for quick color changes as opposed to the older which is siphon.
A cheaper brush may copy the design and material, but if it isn't machined and assembled as well, it can't function as well.
Cheap has it's place, if you're spraying odd materials or glues that may screw up your brush, but saving a few bucks upfront on an AB usually means you'll pay for it either in frustration, replacement costs or ruined models.
