Stuart, I started out airbrushing with a really old, pulsing compressor probably made in the 1940s. When it pooped out, I switched over to CO2. I lease two bottles from a welding supply company (
might've been better to buy the bottles outright?) and have them refilled as needed. I always had trouble keeping moisture out of the line with that old compressor and with CO2, it's not an issue. It's quiet and convenient to use. I have no idea about compressed gas prices in the UK and it might not be a viable option for you over there.
Here's a pic showing the setup in my study:
And like you, I've also been thinking of a new airbrush. All my models have been painted with a Paasche Model H, single-action, syphon-feed AB. The design hasn't been changed much since its debut in the '30s. It's a workhorse but obviously has its limitations and thus, I'm thinking about an upgrade! I'll be watching to see what you decide on and then of course, some results!
