Sanyo Eneloop batteries are by far the best quality mainstream rechargeable batteries you can buy.
This deal is excellent value considering DSE sells 4AA Eneloops standalone for $21.99 (http://dicksmith.com.au/product/S4414/eneloop-4-x-aa-ready-t...)
So for $2 less, you get a FREE charger.
Cheapest on Staticice is from Ryda for 4AA without charger @ $19.85, but you need to consider shipping unless you can pickup + DSE is national.
Edit: Fixed link to standalone batteries. Now point to 4AA instead of incorrectly pointing to the 4AAA.
