Couldn't find a new one any cheaper.
Has a price of $150 with free shipping but with the $20 cashback from Brother and the $5 of reward points on registration, you'll only pay $125.
Some shops sell it for a bit more but you have to pay for shipping on top of the price, Harvey Norman still sells this model for the RRP of $229
Plenty of reviews that are mostly 4 and 5 stars.

The same store sells the bigger Brother MFC-J6930DW, it would only cost $170 delivered after cashback and reward points, this is cheaper then some previously listed bargains of this model.
