Hey All,
Ebay is definately the go, would just be nice though to be able to sometimes talk to someone over the phone, or to see some items (eg: stepper motors etc) rather than just forking out $$$ for something you hope like mad actually turns up - I've only been ripped off once but there is always the chance, then you have to rely on Australia Post!
On the subject of recomendations though. I bought all the electronics for my CNC lathe conversion from www.oatleyelectronics.com
They are in Australia.
Great (quick) service, easy to build kits, emailed a few times about different things and have always received a response, don't really sell suitable motors though, but these kits are great for my first CNC adventure, hooked up to some motors and an old computer and it went first go! I know........I'm scared too!!
www.oceancontrols.com.au also has some kits and stepper motors.
Hope this helps someone.
