lito.sf,
Still confused after having read this thread so far? Well, you should be!
For, you see, you've asked a question that CANNOT be answered in a single or unanimous manner. If it could, then there wouldn't be so many brands selling on the market.
So, let me give you my piece of advise here. Think about it:
1. Before you decide what's best for you, go out and get as many specs sheets as you can and then make your personal study and comparison. The net is a great help on this as well.
2. Then study some more and if you need further info feel free to ask your way around,
but do ask about specifications, not about brands... Asking about brands will get you nowhere...
3. Always keep in mind that
there is NO ABSOLUTE "best" and, also, that the best airbrush you can get is the one that
your money can buy.
4. Eventually, after having done as said above, you'll come up with 3 or 4 candidates. Then (and only then) will be the proper time for you to go to the store. Ask the dealer to show the said airbrushes to you, and sense the way each one of them "behaves" when in your hand. Then, all of the sudden, in a pretty strange way at that, ...you'll know. Suddenly, your choice will be more than obvious... Maybe, this has to do with the fact that an airbrush is not just a modeler's tool. It's rather a modeler's
companion in his/her hobby. I still get this feeling when I paint using my 10 years old Olympos HP-101...
Happy hunting...
