Air Brush Advice Please

[rockinhippy]

I fancy treating myself to one of these, but don't really know much about them, so wondered if anyone here does & has any advice

I spotted one in Halfords of all places for around £50, which sounded like a brilliant deal, but I wondered if perhaps too good too be true

Tips & advice greatly appreciated

TIA :)

I've just double checked & THIS is the Halfords - one its not the same one at all

note to self - get eyes tested

Bump :)
