The Mi4c is going cheap from Eternal Team at AliExpress. Grey version only at this price. This is not to be confused with the Mi4 which has the older Snapdragon 801, this packs the same Snapdragon 808 found in the LG G4 and Nexus 5X. It has the Quick Charge 2.0 tech.
Main disadvantage for me would be the lack of LTE band 28 (700Mhz) which Telstra/Optus use a lot.
I bought the Mi4 for my father in law from this seller, and it came in 10 days via DHL. The seller has sold 158,000 items over 5 years.
