My wife and I have gone back to the walled garden that is Apple and are getting rid of our respective 'droids.
Both are unlocked NZ stock purchased from retailers (Sony Store and Warehouse Stationery from memory) though not sure if I have the original boxes/receipts so assume I don't - will update post if I can find them.
The Sony is red/orange and the N5 black, both in good condition, no cracks or noticeable signs of wear. The Z3c is around a year old and the N5 under 2 years. Each have wallet cases (genuine Sony for the Z3C and an Ebay cheapy for the N5).
Having had a look on TM I'm thinking $400 for the Z3C and $300 for the N5 - will include standard postage within NZ or pickup available from Lower Hutt/Wgtn city.
Let me know if I'm off beam with the prices too :)
