So finally after the suggestions of many, I have decided to buy an airbrush for myslef. Though people have suggested the likes of iwata/badger/passche but I currently do not want to go all out super expensive.
These are the two affordable range airbrushes that I have planned to get as a beginner:
1. Aerograph AG-136B
2. Air Brush HS-30
Both are dual-action gravity feed airbrushes and are from Chinese manufacturers.
If anyone has used these, please let me know how they perform.
This is the compressor I am buying along with the airbrush:
