This is what obd2 Australia has sent me. I haven't looked at prices.

I'm afraid we don't have any plug-and-play scanners for your car; we only have an OBD to USB cable:

and you'll need software called 'TECHSTREAM' to run diagnostics, as well as a Windows device.
If your car has the 22-pin port you'll need this adapter as well:
