recently purchased on fleabay and would recommend a package of Vallejo Air Camo colours which also contains a H&S Ultra on for around £70ish as the H&S Ultra is around £60 on its own, and the set of 10 camo colours on its own would be around £30ish, so would recommend keeping an eye open for bargins on fleabay.
The H&S Ultra is stated by H&S as their entry level/beginners airbrush, and now that I have used it, I prefer this to my Iwata Revolution as it sprays better
