I am interested in getting a kit and have looked on e-bay but all the kits there originate from the US. I don't want to get stung paying all the duty so is there somewhere in Canada that I can get a decent kit from and maybe inexpensive.
Yup..both Flour Confections and Cake Mischief sell airbrush kits.One is located in Toronto the other out of Edmonton.
..Also, bear in mind that you can use a craft airbrush set; doesn't have to be specific to cakes (although obviously the brush part has to be used only for cakes).
I bought my kit from a craft store.
