I love my Badger 150 also, while I know some do not. It is all a matter of preference. I have been using it for so long, that I am just used to it.
As for Tamiya brushes...they are the best IMO. They are made by Iwata, so their quality is very high. Like I said in my earlier post...I have a HG Super Fine, which has a .2mm nozzle (about .3 mm less then the Badger 150's fine nozzle). It is perfect for getting that camo crisp, with limited overspray.
Only downfall with the Tamiya brushes is the air nozzle, which needs an Iwata hose or adaptor to fit to aztec and or Badger compressors. Other then that, I highly recommend any Tamiya Airbrush.
