djmr2 - I agree the CS would be sufficient for larger scale models, it's the BS that I am unsure about. I want to get the BS because it is slightly more compact, but worried whether the 1/16 oz. cup may be a bit small. I know I sounded a little confusing in my initial post, but please bear with me as I have inhaled a little too much primer in these couple days.
I am thinking of buying these tools from dixieart.com instead of buying local since the prices are cheaper. I think I read somewhere that Iwata made their airbrushes in the USA so that means I don't have to pay any duty when importing one into Canada.
freakray - So the pressure regulator and water trap on the Smart Jet a combo unit? If I replace the pressure regulator, where would I put the water trap? I haven't used a compressor before (other than the ones for bicycle tires) so I am still a little confused. Don't forget to post pics when you are ready to do the swap.
