I would have a look around for a Sparmax compressor - they are more expensive than anything that originates from China, but that are less expensive than comparative Iwata models.
As far as I'm aware virtually all airbrush compressor currently originate from either Sparmax in Taiwan or "choose your brand" from China.
Sparmax units are of good quality, well made & specified, Iwata's compressor range is manufactured by Sparmax (as is Revells (GmbH)).
The Chinese units, which are sold under a plethora of house & no names brands are capable & exceptionally cheap, but quality control is a issue, particularly on the tanked models. Longevity also seems to be an issue...
