Ok so, time to take the plunge.

This is my shopping / kit list, what am I missing?

Airbrush (gravity feed)
Compressor
Cleaning stand & solution
Paint station (box / fan / light etc depending how fancy my budget is)
Painting / dust masks
Surgical gloves
Pipettes (for measuring)

I'm using GW acrylic paints, can I thin with water or do I need proper acrylic thinner? Any reccomendations?
Do I need painting / dust goggles?
Should I invest up front in spare parts?

I am a perfectionist so would rather invest in having a quality setup now, than buy stuff I just replace later with better stuff.
