(NOTE: Updated on November 14, 2013.)
Retina display version of the iPad mini is now available. Order online now and expect to wait 1-3 days for the Wifi 16 & 32GB models and 5-10 days for the rest of the models.
Prices start at S$548 for the wifi 16GB model. My recommendation would be the 128GB Wifi Cellular model at S$1148.
