Was searching around for a replacement One Touch drive and found Officeworks have them on clearance.
Only compared the 2TB @ $87, best I could find on the web from a quick search was +/- $100 from Bing Lee.
The 1TB and 4TB as also on clearance. Not sure if they are cheap as I was only looking at the 2TB version.
Hope this might help others.
Happy buying all!
