i know the diffrence between double and single, do you use one more than the other?
id say the lion share of my work is done on the 155. I use the 200 when I am doing large areas.
Curious which Badger 155 and 200 you get? The Badger 155 has pretty large nozzle and the needle makes it very easy to paint large area. You barely touch the trigger, paint comes out like a floodgate. The Badger 200NH has the same characteristic. The 200 old style (the original) has the Badger 100 series nozzle/needle set and should be better for general purpose or finer detail work.
Badger has the 3155 model which is the Badger 155 body with a "fine" needle. I once had this fine nozzle/needle set (0.5 mm) on a Badger 105F Patriot. It still have the quick paint release type character and is good for painting larger models. I did not keep the 105F for long because I am more used to linear, gentle trigger action of the Iwatas. You can get the linear trigger action from the Badger Krome or Renagate Velocity models if you like it.
As I said in earlier post, the choice of airbrush is very personal. Modeler has different perferrence and must test it out himself.
