Consistency of paint is always a tricky one, you need to play about with it, it's sort of a learnt thing and also a lot to do with personal preference. If it's thin and you spray low pressure it will be okay but if it's too thin and you're pressure is too high it will spider everywhere. Likewise if you have it thick and the pressure is too low it will splatter. You really need to play about with it. Ideally about the consistency of Milk. So imagine you'd spilt some milk on a coloured surface, you can just see the colour through it, about like that. Best thing to do is experiment. The 2:1 ration is always a good starting point. I don't measure anything though, just by eye. When you've been doing it a while you can normally tell what's going to work.
Everythingairbrush.com are also good stockist. They do cheap iwata copies and if you're just using waterbased are good enough for block colours and fades. If you want to move onto doing proper artwork and other custom painting I'd get the Iwata, if it's just shells you could get the cheaper one and save yourself a lot of money.
