$345 for a Dell S2740L 27" IPS Monitor from iibuy.com.au
Comes with all the security that Dell warranties etc offer. Price on the Dell site at the moment is $439 (http://accessories.ap.dell.com/sna/productdetail.aspx?c=au&l=en&cs=audhs1&sku=210-40890) and the average elsewhere - using MSY as the benchmark is $400.
So feasibly your paying only $354 for the monitor delivered. Good price for a decent size HD monitor.
