[Procon Boy PS-267 vs PS-270]

Way ahead of you, the order is in. Thanks for all the info, the garden hose comparison by ElectroSoldier is a great analogy. I would never have guessed that the pressure coming out of the airbrush could be greater than that coming out of the compressor.

[Procon Boy PS-267 vs PS-270]

After fighting it for a long time I am ready to jump into the wonderful world of airbrushing. I received an Iwata Revolution CR .5mm for Christmas (thanks Santa) which I am planning on using as my general purpose airbrush (and might convert to .3mm when I get some experience under my belt). Thanks to my OCD (and having yet to fire my Revolution in anger) I am already shopping for a detail brush with a .2mm, e.g. Procon Boy PS-267, PS-270, Tamiya HG III SF, or Grex XGI2-ES which you can pick up for a reasonable price all in the neighborhood of $95-$115. H&S prices are no bueno in comparison. I had a couple questions for those that are knowledgeable about the Procons:

 

1) The PS-267 is approx $20 cheaper than the PS-270, are the only differences the MAC valve and the angled connector, or does it go deeper than that?

2) Being a newbie I don't think I need the added complication of a MAC valve but if someone could illustrate the practical advantages of having it that would help.

3) I mainly build 1/48 WW2 aircraft, does the .2mm/.5mm lineup make sense?

 

Any feedback is greatly appreciated.
