Ryobi have discontinued this model, and Bunnings Bayswater (VIC) had it marked at $99 (clearance), asked for a discount and was happy to pay $80.
Listed on the bunnings website with the battery and charger for$329, http://www.bunnings.com.au/ryobi-one-36v-330m-cut-cordless-l...
I originally got this system last year with this Ryobi promo http://www.ozbargain.com.au/node/67290
I'm pretty sure I got the last one at Bayswater, but you can try other stores.
For this to work you must already have the 36v battery and charger, as can be used in many other Ryobi products including chainsaw, blower, lawn mower etc.
Hope this helps someone else.
