Have spent best part of the day looking at youtube reviews on all sorts/makes of airbrushes, lots of opinions with predictable contradictions.
Anyway Stan gave me the name of a company not far along the coast from where I live and suggested giving them a call - which I did. Thanks Stan.
They couldn't have been more friendly and helpful, and were very willing to give a numpty like me the time of day.
They stock Iwata, Badger, Paasche and Sparmax so a reasonable choice. If I visit them they will advise and show me suitable brushes and allow me to try out the most suitable models - what a result.
So hopefull I'll be doing that next week.
Compressor is sorted - I'll be buying Bartsharp.
