Just bought Canon CanoScan 9000F flatbed scanner from Amazon to make digital copies of my old photos & 35 mm negatives. Local price for the same model is between $300-$400. I checked BH photo video but they don't post scanners to Australia.
Most of the scanners from USA work on 100-120VAC 50/60 Hz but the CanoScan 9000F specifications show that it can work on 100-240VAC (50/60 Hz) power supply. Even if it does not work on Australian power supply you can buy a power converter (about $25) http://www.ebay.com.au/itm/200W-STEP-DOWN-TRANSFORMER-STEPDO…. Still works cheaper than local price.

Edit: I checked with Canon USA and they said that the scanner will work on 100-240V (50/60 Hz) power supply. It looks like it does not require a step down transformer.
Wow, I still have a Canon 8800F which I bought from Officeworks for ~$250 with a cashback offer way back in 2007. Enclosure looks exactly the same. Pretty surprised at the local price for the 9000F now considering our dollar was worth around 60 US cents in 2007! :)
I just checked the power supply for my 8800F (which I suspect is shared with the 9000F) — it's 100-240V.
