Tjena Peter! Welcome to Armorama.
I bought my H&S evolution airbrush a few years ago based purely on the opinions on nearly every member of IPMS Stockholm who had one, as all were so pleased with it.
The evolution had the 0.2mm and 0.4mm needles/nozzles included, and I bought the quickfix later. Eventhough the brush is good, the quickfix is a must for ease of use.
Since the day I bought it, I have never used the 0.4mm needle/nozzle, and really want to buy the 0.15 set-up. I think it cost around 500:- from Johnny Puma.
As the infinity is a step up ... or at least has all the good parts included, you have an excellent brush, that will make sparying fun and not a chore. I started out with a Clas Ohlsson brush and it simply should not be mentioned in the same sentence as a H&S brush.
