I've been looking for an airbrush also.
Just checked out VenusArt and Nanyang a few weeks ago. Actually had decided on buying from VenusArt, but after I withdraw money, the shop was already closed...
Maybe a good thing... save me from impulse buy

At the same time, I also heard that there's a big Arts supplies store called ArtsFriends at UE3. Heard from friends who buy pottery clay and paints from there. Supposedly much cheaper stuff than elsewhere. This is a chain from S'pore, where they've got 2 stores at BrasBasah and Takashimaya... So, maybe they are the Carrefour of arts stuff.
Just asking if anyone knows that area, and have seen whether they've got airbrushes & compressors or not?
Eitherway, I'll probably want to check out UE3 first before going back to Venus Art again.
Nanyang has Japan made Holbien ABs only.
Their compressor is huge, rm780, no moisture trap, and boss doesn't know specs. Last unit there. So, highly uninterested.
VenusArt is better for compressors. Cheapest one I've seen so far. With moisture trap and pressure gauge etc. The boss keeps recommending the one with the air-tank.
The one with no airtank is rm4xx. But must switch off after 25-30min. Else will overheat and break. And there's no warranty.
The one with airtank is rm180 more expensive. Has auto-off. When airtank is full, it doesn't run continuously. So, can use longer. Less likely to breakdown. No need to worry that you'll forget.
But am still wondering whether can just get a small motorbike compressor and use it. Minimal investment. And later, if lose interest to do AB, can still use it to open motorcycle garage.
