I have purchased a few electrical goods from the US, inclusive of Pioneer dj gear. I have never had any issues with it over the last 3 years I have owned it.

The only one to watch for is the amount of power the unit requires to run, opposed to the amount of power the converter can convert down to 110V. Basically, just make sure you buy a decent converter and you should be fine.

Don't forget about the tax incurred if over $1000 AUD
