Harder Steenbeck Hansa or Evolution

Please notice that Hansa is a brand like Harder & Steenbeck; it belongs to Harder & Steenbeck like Thayer & Chandler belongs to Badger, so I bet the general engineering quality of both is similar; but there are a number of Hansa that use what is called synchronized double action (I think that H&S Grafo did also but not sure) : instead of having separate control over air and medium flow (be it ink, paint, etc...) the synchronized airbrush has a progressive trigger that controls the whole thing together, er is the more you pull the trigger the more air/medium combination sprays; the only preset you can make is how much the needle is engaged/disengaged at zero point so you can begin with zero to n medium flow to maximum anyway. There are not a lot of those beasts ( I own Gabber PRS who do this and believe that Colanis work this way) . I think this is because this process is far less popular than the independent double action. I advocate you try one of those before buying as the feeling is a bit different. 

As Torio says, the Hansa models are H&S's "entry level" models & feature a progressive air then paint trigger action in a similar fashion to the Colani & the Grex trigger brushes. If you are used to a double action brush I would suggest getting a feel of the Hansa brush first.

Many seem to incorrectly interpret that double action have proper control over the air flow as well as the paint, but as a long rumbling thread recently suggested, this is not the case. The air output on double actions can be controlled in a very slight, but pretty much unrepeatable fashion - this is a by-product of the air valve operation as opposed to a designed feature. The usually & accepted method of air flow control is by regulation, weather it be at the compressor or via an add-on in-line valve.

Weather this type of trigger action is better or worse seems to be a matter of opinion.  

The gent at Chicago Airbrush gave a strong thumbs up to the Evolution especially as I was already used to a standard double action. Looking forward to trying it out. Thanks for help.

And if you choose this one, you'll see it is very...evolutive, be it for needle/nozzle gauges or for cup dimensions. Consider also the quick stop needle traveler (not the standard one of the Silverline, the other one that also goes standard with the Infinity) As for me, I also purchased caps for my cups. One last thing : you"ll need a quick connect/disconnect airhose.
