First up, welcome to airbrushing! Its wicked fun!!
My main advice when shopping for your first setup is to be more interested in having a good compressor, if as you say money is no issue; theres a huge choice for you my friend! its really quite easy when someones on a tight budget to suggest an AS186,they're great little machines that you could get away with running in your home.
With more money there are some really nice looking, genuinly really quiet machines from iwata and some other brands. 'Bambi' could be a good name to look at, they make dentist quality air sources and hence tend to be a little more up market than airbrushings absolute minimum. But cleaner air is better and its not going to get much cleaner than at the dentists?!
For your first setup the compressor is much more important than the brush. Why? Because 95% of us break our first airbrush as part of the learning how to care for your brush properly stage in the learning curve.
It can be tempting to look at the top end like iwata micron's and other micro fine tip brushes
But you dont really know how to make use of it yet and will probably struggle much more with it to start with to be brutally honest. A cheap china special 0.3mm would likely do you almost aswell for starting out.
The full setup you linked with the iwata eclipse looks great to me! I've never had an iwata brush in my hands but I dont doubt that theyre top notch (I use a Harder & Steenbeck Evolution), The Eclipse is iwata's mid rangey medium tip size area brush which should be just what you want for priming, basecoating and shading mini's with thinned acrylics.
The paints they give you in the bundle (createx) are decent paints, I'm not sure about for mini's but they do ahdere to fabrics well - I'd use those for custom tee shirt painting and that kind of thing.They can be thinned down a crazy amount and still spray okay; the insane freehand detail painting is done with over thinned paints and realy low airpressures.
The compressor in the bundle is an AS186 which is perfectly fine and will provide all the pressure you need for airbrushing, its mildly noisy, I have an AS196 which is the same except twin pistons so would be louder and fill up faster. Its good for working about an hour at a time before it wants to cool off ( they spit moisture more when hot, condensation and all that)
I didnt get into airbrushing via the figure painting hobby, and already had my airbrush before. For paints I just use Liquitex Airbrush medium with
GW colours on my mini's and havent had any problems yet with my 0.2mm tip. For my regular airbruhsing on other surfaces I use acrylic inks (usually Liquitex brand but theres others) or thinned artist acrylics (with the liquitex medium).
If you were looking for some paints specifically for airbrushing models with... the general consensus seems to be vallejo model air is a good system. all prethinned in dripper bottles ready to go with minimum hassle. I'm still keen to try these out myself, but dont really need to becuase I can thin my own just as happily and have plenty of supplies from my other arty projects.
If you get stuck or need help with anything, or more info on anything specific just holla
I'm happy to try and help as are many of the others here.
