Hi all, Costco have further reduced the price of this rotary tool. Same tool as in this ozbargain https://www.ozbargain.com.au/node/118035
As notedby Doperst in that bargain, the few reviews on Amazon generally aren't too complimentary. However, given the price on Amazon is US$32.33 plus postage, at under twenty bucks it seems like good value. The cheapest price I can find on Ebay is around $80 shipped (and then you'd have to worry about the voltage).
If you did want to spend more, Bunnings sell an Ozito with a flexible shaft and a 218 piece kit for $39.95.
I bought one, I'll try it out over the weekend and put an update in the comments.
Spotted in Costco Docklands - unsure of other stores.
I have the ozito one from Bunnings and its nothing flash
