Just bought one today and it seems to be a good printer. The price is $264 but got it for $250. Bonus $50 gift card as well. If you want to try Officeworks' price match thing it will be a bit more cheaper but I couldn't be bother.

With the cost of ink these days I rarely think its a good idea to shell out over 200 bucks on a printer.
I don't really understand why people buy expensive home printers. Unless you plan on printing your own photos, which you shouldn't because getting them done at shops is so cheap.
Apart from the printing quality and convenience, this one includes a great scanner, automatic duplexer and wireless networking support. Also, more expensive models may be built to last a little longer. The capacity of the initial ink/toner cartridges and the running costs per page may also matter.
BTW, if you are looking at MG8150, have a look at MG6150 as well.

Officeworks @ $199 + $50 voucher
Meh looks like it was an estore price match
EStore had it for $199. And OP was able to get OW to price match
Unfort eStore has upped their price
Considering it's a 20% difference of what it could have been bought at I do not find this a bargain.
