Airbrushes - any recs? Or (London-area!) loans?

[pseudomonas]

So, following the Trojan Pony, which was done with spray-can primer and manual paintbrushing, I'm thinking of another daft custom, but this one might want an airbrush. I've done some reading online, as you do, and it looks like getting a no-name £5 airbrush new on eBay is a false economy and I probably want a more robust brand-name one.

Does anyone have any recommendations or things to consider? Or, does anyone approximately in the London (UK) area feel like lending me an airbrush/compressor for a week at some point so I can get the feel of it?
