Hi Noel,
I bought this airbrush a few years ago: https://www.ebay.ie/itm/Dual-Action-0-2mm-9cc-Needle-Airbrush-Spray-Gun-Air-Brush-For-Model-Paint-Tattoo/301976438859?hash=item464f32c84b:g:IkYAAOSwvg9XVOsg
I think it is very good, dual action with a trigger limiter. I dismantle mine completely when cleaning and it is still working well. The paint flows well and it comes with a few needle sizes.
