You can buy the same brand tyre air fittings as what they use at the garages. I think the common brand is JP. But don't forget, the reason why the garages dont work half the time which ****es me off a bit is that every Tom, Dick, and Harry use them. They chuck them about and treat them roughly. If you bought one for yourself it will be okay to use for a very long time. I have a feeling they are around the $50 mark.
Cheers,
