when looking for an air brush and compressor type, what sort of criteria do you look for in term of quality built, functionality , easy cleaning and maintenance?

I know there's a few suppliers in lelong didn't mentioned much about the brand and where it's made. Before i invest a lot of money into this , i like to know if my investment in getting a good one will save more in long term rather than invest cheap but faced with a lot of maintenance issue and the cost.

Sometimes cheap may not be that good, the mechanism won't last long or the technology is old. So i like to know from you guys if there's any thing that's is in the latest tech for air brush and compressor . thanks.
