Whilst not an epic deal, it's a decent price.
Been looking for a "cheap" 2 bay Synology for my Dad and $158 is a lower price than I've seen it recently, the shipping is standard Aus Post rates, worked out to ~$13 for me in Perth. They also have the DS216j for $198 but that's closer to the "standard" pricing, although still slightly cheaper.
Check the link for all the product specs — I'm too lazy to OzB format it, click the link. Look, I'll even throw in a link to the Synology page.
At $168.25 shipped to Melbourne, its 75cents cheaper than the local shop.. pass!
